    Pathways Their Myriad Phytochemicals: of Biological Activities and Production Hemp

    It is known that induction of enzymatic activity in early steps of a biosynthetic pathway precedes the accumulation of final products Fig. The cannabinoid content in female flowers from drug-type plants Skunk and Fourway varieties was five times higher than the flavonoid content, but in female flowers from fiber-type plants Kompolti variety it was only twice the amount Tables 1 , 2.

    During the development of the glandular trichomes on the flowers, the activity of the olivetol-forming PKS at day 29 was seven times higher than the CHS activity Fig. Although, STS activity detected during the time course was low, it increased at the end, being five and 18 higher than the CHS and olivetol-forming PKS activities, respectively. This STS activity can be associated with precursor formation in stilbenoid biosynthesis.

    Using the present approach, we believe that we have clear evidence for the presence of different PKS profiles in the different tissues; which are further supported by the phytochemical analyses of these tissues. The role of olivetol synthase in the plant needs further clarification.

    Its activity coincides with the occurrence of the cannabinoids. On the other hand, no activity of olivetolic acid synthase has been found in cannabis so far. This raises the question about whether the in planta activity of this enzyme could be different from its in vitro activity. Further studies are required to identify the substrate specificities of these individual PKS enzymes in cannabis plants. Purification and characterization of the PKS enzymes will be necessary to determine their catalytic potential and regulation, which may lead to the identification of their role in the plant.

    Proposed reactions for PKS enzymes in the biosynthesis of precursors from flavonoid, stilbenoid and cannabinoid pathways in cannabis plants. The dashed square represents the compound found in crude extracts. After 3 weeks, the small plants were transplanted into 10 liter pots for continued growth until flowering.

    Five day-old seedlings, young leaves from week-old plants, female flowers and bracts at different stages of development, and male flowers from 4-month-old plants were harvested. Three-month-old male plants were used for pollination of female plants. The fruits were harvested 18 d after pollination. Roots from 4-month-old female plants were harvested and washed with cold water to remove residual soil.

Medical uses of marijuana Cannabis sativa: Marijuana Cannabis sativa has been used throughout the world medically, recreationally and spiritually for thousands of years. In South Africa, from the midth century to the s, practitioners prescribed it for a multitude of conditions.

    In it was classified as a Schedule I substance, illegal, and without medical value. Ironically, with this prohibition, cannabis became the most widely used illicit recreational drug, not only in South Africa, but worldwide.

    Cannabis is generally regarded as enjoyable and relaxing without the addictive risks of opioids or stimulants. In alternative medicine circles it has never lost its appeal. To date 23 States in the USA have legalised its medical use despite the federal ban. Unfortunately, little about cannabis is not without controversy. This system's elucidation raises the possibility of many promising pharmaceutical applications, even as restrictions show no sign of abating. Recreational use of cannabis continues to increase, despite growing evidence of its addictive potential, particularly in the young.

    Public approval drives medical cannabis legalisation efforts without the scientific data normally required to justify a new medication's introduction. This review explores these controversies and whether cannabis is a panacea, a scourge, or both. Proline and phenolices were correlated with Cd contents in plant.

    Cd significantly reduced the plant growth. Fertilizers application in combination most significantly increased the growth 19 cm root and 47 cm shoot on Cd contaminated soil. All treatments increased the Cd contents in plant tissues.

    This increase was highly significant in fertilizers treated plants , and ppm in roots, stem and leaves respectively. All treatments significantly increased the proline and total phenolics and maximum was recorded in NaCl treated plants followed by fertilizers.

    Proline was higher in roots while phenolics in leaves. Proline and phenolics showed positive correlation with Cd concentration in plant. Conclusively, fertilizers in combination seem to be the better option for Cd phytoextraction. Further investigation is suggested to study the role of phenolics and proline in Cd phytoextraction. In many parts of the world, the possession and cultivation of Cannabis sativa L.

    As chemical or morphological analyses cannot identify the plant in some cases, a simple yet accurate DNA-based method for identifying C. We have developed a loop-mediated isothermal amplification LAMP assay for the rapid identification of C. The detection limit was the same as or higher than that of conventional PCR. Using a simple protocol, the identification of C.

    A rapid, sensitive, highly specific, and convenient method for detecting and identifying C. Sensitization and allergy to Cannabis sativa leaves in a population of tomato Lycopersicon esculentum -sensitized patients. Cases of allergy to Cannabis sativa have occasionally been reported, but both the allergenic profile and eventual cross-reactivity pattern remain unknown.

    To analyze the allergenic profile of a population of patients from Spain sensitized to C. A total of 32 subjects were enrolled in the study: Sensitivity to Cannabis , tomato and peach peel, Platanus hybrida and Artemisia vulgaris pollen extracts was measured by skin tests and specific IgE.

    Individual immunoblots and inhibition experiments with a pool of sera were conducted. All tomato-sensitized subjects and 1 negative had positive skin tests to C. Specific IgE to C. Immunoblot experiments showed 2 prominent bands of 10 and 14 kDa and 2 weakly recognized bands of 30 and 45 kDa. Tomato, peach and A. Gene duplication and divergence affecting drug content in Cannabis sativa.

    Marijuana and hemp were crossed to evaluate competing models of cannabinoid inheritance and to explain the predominance of tetrahydrocannabinolic acid THCA in marijuana compared with cannabidiolic acid CBDA in hemp. Individuals in the resulting F2 population were assessed for differential expression of cannabinoid synthase genes and were used in linkage mapping. Genetic markers associated with divergent cannabinoid phenotypes were identified. Phylogenetic analysis further suggests a history of duplication and divergence affecting drug content.

    Marijuana is distinguished from hemp by a nonfunctional CBDA synthase that appears to have been positively selected to enhance psychoactivity. An unlinked QTL for cannabinoid quantity may also have played a role in the recent escalation of drug potency.

    Legal limits on the psychoactive tetrahydrocannabinol THC content in Cannabis sativa plants have complicated genetic and forensic studies in this species. However, Cannabis seeds present very low THC levels. We developed a method for embryo extraction from seeds and an improved protocol for DNA extraction and tested this method in four hemp and six marijuana varieties.

    This embryo extraction method enabled the recovery of diploid embryos from individual seeds. DNA extracted from embryos was used for SSR molecular characterization in individuals from the 10 varieties.

    A unique molecular profile for each individual was obtained, and a clear differentiation between hemp and marijuana varieties was observed. The combined embryo extraction-DNA extraction methodology and the new highly polymorphic SSR markers facilitate genetic and forensic studies in Cannabis.

    Material is typically identified based on the cystolithic hairs on the leaves and with chemical tests to identify of the presence of cannabinoids.

    Suspect seeds are germinated into a viable plant so that morphological and chemical tests can be conducted. Seed germination, however, causes undue analytical delays. DNA analyses that involve the chloroplast and nuclear genomes have been developed for identification of C.

    Using the trnL 3' exon-trnF intragenic spacer regions within the C. This assay provides forensic science laboratories with a quick and reliable method to identify an unknown sample as C. Because of limitation in cultivation of this plant , an efficient hairy root induction system for Cannabis sativa L. Molecular analysis of transformed root lines was confirmed by polymerase chain reaction using specific primers of the rolB gene. The transformation frequency by Murashige and Skoog co-cultivation medium resulting in hairy root induction frequencies of This study established a reliable protocol for induction of hairy roots of C.

    Metals and organic compounds in the biosynthesis of cannabinoids: Illicit production and trade of Cannabis sativa affect many societies. This drug is the most popular and easy to produce. Important information for the authorities is the production locality and the indicators of a particular production. This work is an attempt to recognise correlations between the metal content in the different parts of C. In this study, numerous correlations between metal content in plants and soil, already confirmed in previous publications, were analysed applying chemometric unsupervised methods, that is, principal component analysis, factor analysis and cluster analysis, in order to highlight their role in the biosynthesis of cannabinoids.

    Heat exposure of Cannabis sativa extracts affects the pharmacokinetic and metabolic profile in healthy male subjects. Cannabidiol CBD , another important constituent, is able to modulate the distinct unwanted psychotropic effect of THC. In natural plant extracts of C. Therefore, in the present study, the pharmacokinetics and metabolic profiles of two different C. The pharmacokinetics of the cannabinoids was highly variable.

    The metabolic pattern was significantly different after administration of the different forms: The later was slightly higher than that of dronabinol 4. These results indicate that use of unheated extracts may lead to a beneficial change in metabolic pattern and possibly better tolerability.

    Trichomes of Cannabis sativa as viewed with scanning electron microscope. Direct examination of fresh, unfixed and uncoated specimens from vegetative and floral parts of Cannabis sativa with the scanning electron microscope enables one to obtain a faithful representation of their surface morphology. The presence of two major types of trichomes has been confirmed: Moreover, three or possibly four distinct glandular types can be distinguished: The nonglandular trichomes can be distinguished by the nature of their surfaces: The range of size and distribution, and the special features of all these types of trichomes are also provided.

    Cannabis Cannabis sativa L. At the University of Mississippi, different strains of C. A GC-FID method has been developed and validated for the qualitative and quantitative analysis of acid and neutral cannabinoids in C. The method involves trimethyl silyl derivatization of the extracts. The limit of detection range was 0. The developed method is simple, sensitive, reproducible, and suitable for the detection and quantitation of acidic and neutral cannabinoids in different extracts of cannabis varieties.

    The method was applied to the analysis of these cannabinoids in different parts of the micropropagated cannabis plants buds, leaves, roots, and stems. Prevalence of sensitization to Cannabis sativa. Lipid-transfer and thaumatin-like proteins are relevant allergens. Although allergy to Cannabis sativa was first reported over 40 years ago, the allergenicity has scarcely been studied.

    The objectives of this study were to investigate the frequency of sensitization to this plant , to analyze the clinical characteristics and allergenic profile of sensitized individuals and to identify the allergens involved. Five hundred and forty-five individuals in Spain attending allergy clinics with respiratory or cutaneous symptoms underwent a skin-prick test SPT with C. Of this preselected population, 44 individuals had positive SPT to C.

    Prevalence was higher in individuals who were C. Two individuals reported mild symptoms with C. Twenty-one individuals from 32 available sera Twelve sera recognized at least 6 different bands in a molecular-weight range of between 10 and 60 kDa. Six of them recognized a kDa band, identified as a lipid transfer protein LTP and 8 recognized a kDa band, identified as a thaumatin-like protein.

    There is a high prevalence of sensitization to C. The clinical symptoms directly attributed to C. The sensitization profile observed suggests that C. The effect of hydroalcoholic extract of Cannabis Sativa on appetite hormone in rat. Ghrelin is an orexigenic peptide which is secreted from stomach.

Molecular cytogenetic characterization of the dioecious Cannabis sativa with an XY chromosome sex determination system. The karyotype has 18 autosomes plus a sex chromosome pair XX in female and XY in male plants. The autosomes are difficult to distinguish morphologically, but three pairs could be distinguished using the probes.

    The X is the largest chromosome of all, and carries CS-1 subtelomeric repeats on both arms. The meiotic configuration of the sex bivalent locates a pseudoautosomal region of the Y chromosome at the end of the euchromatic CScarrying arm. Our molecular cytogenetic study of the C.

    Trichomes, especially the capitate-stalked glandular hairs, are well known as the main sites of cannabinoid and essential oil production of Cannabis sativa. In this study the distribution and density of various types of Cannabis sativa L trichomes, have been investigated by scanning electron. Induction of mutants in Cannabis Sativa L. A description is given of the mutations induced in a well known cultivar of fibre hemp belonging to the species Cannabis sativa in order to obtain new phenotypic characters that could unequivocally differentiate it from drug hemp.

    These new cultivars, named red petiole exhibiting anthocyanin leaf petioles and yellow apex exhibiting yellow distal leaflets , have been compared with varieties C. These agronomical trials highlighted the good performance of both new cultivars as for yield in dry matter and in fibre, not significantly different from the results of carmagnola. Besides, the new cultivars showed THC contents 0. Minor oxygenated cannabinoids from high potency Cannabis sativa L.

    Nine oxygenated cannabinoids were isolated from a high potency Cannabis sativa L. Diversity analysis in Cannabis sativa based on large-scale development of expressed sequence tag-derived simple sequence repeat markers. However, lack of sufficient simple sequence repeat SSR markers has limited the development of cannabis genetic research. Here, large-scale development of expressed sequence tag simple sequence repeat EST-SSR markers was performed to obtain more informative genetic markers, and to assess genetic diversity in cannabis Cannabis sativa L.

    From there, a total of 3, complementary primer pairs were designed as SSR markers. Among these markers, trinucleotide repeat motifs Among these markers, Forty-five polymorphic primer pairs were selected to evaluate genetic diversity and relatedness among the cannabis genotypes.

    The results showed that varieties could be divided into 4 groups primarily based on geography: Moreover, the coefficient of similarity when comparing cannabis from Northern China with the European group cannabis was higher than that when comparing with cannabis from the other two groups, owing to a similar climate. This study outlines the first large-scale development of SSR markers for cannabis. These data may serve as a foundation for the development of genetic linkage, quantitative trait loci mapping, and marker-assisted breeding of cannabis.

    In silico discovery of terpenoid metabolism in Cannabis sativa [version 1; referees: Full Text Available Due to their efficacy, cannabis based therapies are currently being prescribed for the treatment of many different medical conditions.

    This recommendation of the Italian National Toxicological Committee CCTN regards the possible toxic effects of some products derived from Cannabis sativa , indica variety.

    The CCTN has especially evaluated genotoxic, immunological and toxic to reproduction effects of these substances, on the basis of the results from both experimental studies and observations on humans.

    The effect of tetraploidy induction on morphology and anatomy characteristics of Cannabis sativa L. Flow cytometry analyses were used to confirm the ploidy level. Morphologic and anatomic characteristics between tetraploid and diploid control plants were compared. The results showed that 0. The percentage of tetraploid plants and the survival rate were lowered by increasing the treatment time. In addition, the leaf index and height of tetraploid plants exhibited a significant decrease compared to the diploid plants.

    The size of leaves' epidermis stomata were larger in tetraploid plant compared to the diploid ones, in spite of their less density of stomata. However, the amount of total chlorophyll and carotenoids were almost the same in both of tetraploid and diploid plants. In addition, some differences were also observed in the cross section of stem of these plants from the descriptive structure point of view.

    On the whole, the results introduced usage of the stomata parameters as an effective and convenient method for detecting the tetraploid plants however, the flow cytometry analysis was more effective in assessing the ploidy percentage.

Haloperidol is a classic antipsychotic drug known for its propensity to cause extrapyramidal symptoms due to blockade of dopamine D2 receptors in the striatum.

    Interest in medicinal uses of cannabis is growing. Cannabis sativa has been suggested as a possible adjunctive in treatment of Parkinson's disease. The present study aimed to investigate the effect of repeated administration of an extract of Cannabis sativa on catalepsy and brain oxidative stress induced by haloperidol administration in mice. Mice were euthanized 18 days after starting cannabis injection when biochemical assays were carried out.

    Mice treated with cannabis and haloperidol showed significant decrease in catalepsy duration, compared with the haloperidol only treated group.

    This decrease in catalepsy duration was evident on days after starting cannabis injection. Later the effect of cannabis was not apparent. Glucose in brain decreased by The administration of only haloperidol increased MDA Monitoring Metabolite Profiles of Cannabis sativa L. Cannabis sativa trichomes are glandular structures predominantly responsible for the biosynthesis of cannabinoids, the biologically active compounds unique to this plant.

    To the best of our knowledge, most metabolomic works on C. Partial least squares discriminant analysis models successfully classified metabolites of the trichomes based on the harvest time. According to RT-PCR analysis, gene expression levels of olivetol synthase and olivetolic acid cyclase influenced the accumulation of cannabinoids in the Cannabis trichomes during the monitoring time. Effect of induced polyploidy on some biochemical parameters in Cannabis sativa L.

    This study is aimed at testing the efficiency of colchicine on inducing polyploidy in Cannabis sativa L. Shoot tips were treated with three different concentrations of colchicine 0, 0. The biggest proportion of the almost coplanar tetraploids The ploidy levels were screened with flow cytometry. The biochemical analyses showed that reducing sugars, soluble sugars, total protein, and total flavonoids increased significantly in mixoploid plants compared with tetraploid and diploid plants.

    Tetraploid plants had a higher amount of total proteins, total flavonoids, and starch in comparison with control plants. The results showed that polyploidization could increase the contents of tetrahydrocannabinol in mixoploid plants only, but tetraploid plants had lower amounts of this substance in comparison with diploids.

    Also, we found such changes in protein concentration in electrophoresis analysis. In overall, our study suggests that tetraploidization could not be useful to produce tetrahydrocannabinol for commercial use, and in this case, mixoploids are more suitable. The potential of hemp Cannabis sativa L. A comprehensive research programme in the Netherlands has concluded that fibre hemp is a potentially profitable crop, having the right profile to fit into sustainable farming systems. Effect of Ruta graveolens and Cannabis sativa alcoholic extract on spermatogenesis in the adult wistar male rats.

    Ameliorative Efficacy of Nigella Sativa. Cannabis is a widely used illicit drug with various threats of personality syndrome, and Nigella sativa has been widely implicated as having therapeutic efficacy in many neurological diseases. The present study investigates the ameliorative efficacy of Nigella sativa oil NSO on cannabis -induced moto-cognitive defects.

    The Morris water maze MWM paradigm was used to assess the memory index, the elevated plus maze was used for anxiety-like behaviour, and the open field test was used for locomotor activities; thereafter, the rats were sacrificed and their brains were removed for histopathologic studies. Cannabis -like Scopolamine caused memory impairment, delayed latency in the MWM, and anxiety-like behaviour, coupled with alterations in the cerebello-hippocampal neurons.

    The post-treatment of rats with NSO mitigated cannabis -induced cognitive dysfunction as with scopolamine and impaired anxiety-like behaviour by increasing open arm entry, line crossing, and histological changes. The observed ameliorative effects of NSO make it a promising agent against moto-cognitive dysfunction and cerebelo-hippocampal alterations induced by cannabis. Cannabis is a drug derived from hemp plant , Cannabis sativa , used both as a recreational drug or as medicine.

    It is a widespread illegal substance, generally smoked for its hallucinogenic properties.

    Early phenylpropanoid biosynthetic steps in Cannabis sativa: A Vademecum for Molecular Biologists. Full Text Available In plants there is no universal protocol for RNA extraction, since optimizations are required depending on the species, tissues and developmental stages. One such example is bast fibres, long extraxylary cells characterized by a thick cellulosic cell wall.

    Given the economic importance of bast fibres, which are used in the textile sector, as well as in biocomposites as green substitutes of glass fibres, it is desirable to better understand their development from a molecular point of view.

    This knowledge favours the development of biotechnological strategies aimed at improving specific properties of bast fibres. To be able to perform high-throughput analyses, such as, for instance, transcriptomics of bast fibres, RNA extraction is a crucial and limiting step. We here detail a protocol enabling the rapid extraction of high quality RNA from the bast fibres of textile hemp, Cannabis sativa L.

    Compounds 2—4 were inactive as analgesics. Los productos de Cannabis sativa: Safety and side effects of cannabidiol, a Cannabis sativa constituent. Cannabidiol CBD , a major nonpsychotropic constituent of Cannabis , has multiple pharmacological actions, including anxiolytic, antipsychotic, antiemetic and anti-inflammatory properties.

    However, little is known about its safety and side effect profile in animals and humans. This review describes in vivo and in vitro reports of CBD administration across a wide range of concentrations, based on reports retrieved from Web of Science, Scielo and Medline. The keywords searched were "cannabinoids", "cannabidiol" and "side effects".

    Several studies suggest that CBD is non-toxic in non-transformed cells and does not induce changes on food intake, does not induce catalepsy, does not affect physiological parameters heart rate, blood pressure and body temperature , does not affect gastrointestinal transit and does not alter psychomotor or psychological functions. Conversely, some studies reported that this cannabinoid can induce some side effects, including inhibition of hepatic drug metabolism, alterations of in vitro cell viability, decreased fertilization capacity, and decreased activities of p-glycoprotein and other drug transporters.

    Based on recent advances in cannabinoid administration in humans, controlled CBD may be safe in humans and animals. However, further studies are needed to clarify these reported in vitro and in vivo side effects.

    In this study the distribution and density of various types of Cannabis sativa L. Furthermore, glandular trichomes were isolated over the flowering period 8 weeks by laser microdissection LMD and the cannabinoid profile analyzed by LCMS.

    Cannabinoids were detected in extracts of collected cells of capitate-sessile and capitate stalked trichomes and separately in the gland head and the stem of the latter. Cannabichromene [CBC 8 ] along with cannabinol CBN 9 were identified as minor compounds only in the samples of intact capitate-stalked trichomes and their heads harvested from 8-week old plants.

    The hereby documented detection of metabolites in the stems of capitate-stalked trichomes indicates a complex biosynthesis and localization over the trichome cells forming the glandular secretion unit. Nature has developed many pathways to produce medicinal products of extraordinary potency and specificity with significantly higher efficiencies than current synthetic methods can achieve.

    Identification of these mechanisms and their precise locations within plants could substantially increase the yield of a number of natural pharmaceutics.

    In line with previous observations we find high concentrations of THCa in pistillate flowering bodies and relatively low amounts within flowering bracts.

    Cold acclimation induces distinctive changes in the chromatin state and transcript levels of COR genes in Cannabis sativa varieties with contrasting cold acclimation capacities. Little is known about the capacity of Cannabis sativa to cold-acclimate and develop freezing tolerance. This study investigates the cold acclimation CA capacity of nine C. The varieties were divided into three groups based on their contrasting CA capacities by comparing the survival of non-acclimated and cold-acclimated plants in whole- plant freeze tests.

    In response to the CA treatment, all varieties accumulated soluble sugars but only the varieties with superior capacity for CA could maintain higher levels throughout the treatment. In addition, the varieties that acclimated most efficiently accumulated higher transcript levels of cold-regulated COR genes and genes involved in de novo DNA methylation while displaying locus- and variety-specific changes in the levels of H3K9ac, H3K27me3 and methylcytosine MeC during CA.

    Furthermore, these hardy C. This study uncovers the molecular mechanisms underlying CA in C. EB - Genetics ; Molecular Biology. Structural basis for olivetolic acid formation by a polyketide cyclase from Cannabis sativa. In polyketide biosynthesis, ring formation is one of the key diversification steps. Olivetolic acid cyclase OAC from Cannabis sativa , involved in cannabinoid biosynthesis, is the only known plant polyketide cyclase. The crystal structures revealed that the enzyme indeed belongs to the DABB superfamily, as previously proposed, and possesses a unique active-site cavity containing the pentyl-binding hydrophobic pocket and the polyketide binding site, which have never been observed among the functionally and structurally characterized bacterial polyketide cyclases.

    The structural and functional insights obtained in this work thus provide the foundation for analyses of the plant polyketide cyclases that will be discovered in the future. The major degradation products identified were 3-hydroxy-2,4,4-trimethylpentyl2-methylpropanoate and 2-ethylhydroxyhexyl2-methylpropanoate compounds.

    These are found in higher levels in the exhalations of colorectal cancer patients and are similar to the toxic products associated with lipid peroxidation of polyunsaturated fatty acids. In Wistar rats, females treated with BC degraded by CSS BCCSS showed whitish liver spots, alterations in liver weight and in bilirubin and alkaline phosphatase levels, and decrease in the number of leukocytes associated with atypical lymphocytosis.

    In male rats, there was an increase in the number of leukocytes when compared to the control group. In the histopathological analysis, the cortical region of the kidneys showed the presence of discrete amorphous eosinophilic material cylinders in the lumen of the proximate and distal convoluted tubules.

    Molecular cytogenetic analysis of monoecious hemp Cannabis sativa L. Sex expression is controlled by an X-to-autosome balance system consisting of the heteromorphic sex chromosomes XY for males and XX for females. Genetically monoecious hemp offers several agronomic advantages compared to the dioecious cultivars that are widely used in hemp cultivation.

    The male or female origin of monoecious maternal plants is unknown. Additionally, the sex chromosome composition of monoecious hemp forms remains unknown. In this study, we examine the sex chromosome makeup in monoecious hemp using a cytogenetic approach.

    Eight monoecious and two dioecious cultivars were used. All monoecious plants showed female amplification patterns. There was a high level of intra- and intercultivar karyotype variation detected.

    The results of this study can be used for further analysis of the genetic basis of sex expression in plants.
