Previous chemotaxonomic studies of cannabis only focused on tetrahydrocannabinol (THC) dominant strains while excluded the cannabidiol (CBD) dominant strains and intermediate strains (THC ≈ CBD). This study investigated the utility of the full spectrum of secondary metabolites in different plant parts in three cannabis chemotypes (THC dominant, intermediate, and CBD dominant) for chemotaxonomic discrimination. Hierarchical clustering, principal component analysis (PCA), and canonical correlation analysis assigned 21 cannabis varieties into three chemotypes using the content and ratio of cannabinoids, terpenoids, flavonoids, sterols, and triterpenoids across inflorescences, leaves, stem bark, and roots. The same clustering results were obtained using secondary metabolites, omitting THC and CBD. Significant chemical differences were identified in these three chemotypes. Cannabinoids, terpenoids, flavonoids had differentiation power while sterols and triterpenoids had none. CBD dominant strains had higher amounts of total CBD, cannabidivarin (CBDV), cannabichromene (CBC), α-pinene, β-myrcene, (−)-guaiol, β-eudesmol, α-eudesmol, α-bisabolol, orientin, vitexin, and isovitexin, while THC dominant strains had higher total THC, total tetrahydrocannabivarin (THCV), total cannabigerol (CBG), camphene, limonene, ocimene, sabinene hydrate, terpinolene, linalool, fenchol, α-terpineol, β-caryophyllene, trans-β-farnesene, α-humulene, trans-nerolidol, quercetin, and kaempferol. Compound levels in intermediate strains were generally equal to or in between those in CBD dominant and THC dominant strains. Overall, with higher amounts of β-myrcene, (−)-guaiol, β-eudesmol, α-eudesmol, and α-bisabolol, intermediate strains more resemble CBD dominant strains than THC dominant strains. The results of this study provide a comprehensive profile of bioactive compounds in three chemotypes for medical purposes. The simultaneous presence of a predominant number of identified chemotype markers (with or without THC and CBD) could be used as chemical fingerprints for quality standardization or strain identification for research, clinical studies, and cannabis product manufacturing.

Quantitative Screening

Azadirachta indica which is commonly known as neem plant has one of the most promising medicinal properties having a wide spectrum of biological activity. Fresh matured leaves, stem-bark and seeds of A. indica (neem) were collected, air dried and aqueous-extract was used to screen for some active chemical constituents. Phytochemicals of neem plant parts were extracted and screened both qualitatively and quantitatively. The screening of A. indica was carried out at Institute of Agriculture and Animal Science, Paklihawa Campus, Rupandehi in a quest to evaluate the phytochemicals. Among the qualitative tests done for the presence of secondary metabolites; alkaloids, saponins, terpenoids, flavonoids were found to present in all of the tested parts whereas steroids, polyphenols and tannins were present only in leaves and stem-bark. Glycosides and coumarins are absent in all of the tested parts. Quantitative screening was also done by using gravimetric method. Alkaloids were found in all the parts of A. indica with the highest amount of alkaloids were obtained in stem-bark (12.8%) and lowest in leaves (10.67%). Highest flavonoids percentage was revealed in leaves (13.8%) and lowest flavonoids in stem-bark (12.8%). Similarly, seeds (2.53%) contained saponins % while it was lowest in stem-bark (2.50 %). Terpenoids % were similar in both i.e. leaves and stem-bark (13.13%), whereas lowest in seeds (12.77%). More research on secondary metabolites will be helpful to the chemical industries to produce plant-based chemicals and minimize the environment degradation from different synthetic chemicals. Int. J.

In vitro cultures of Hypericum heterophyllum Vent. was established by using MS and MS-B5 medium contained plant growth regulators such as kinetin, BAP, IAA, TDZ and picloram. Flower, leaf, stem and in vitro samples (callus and in vitro plantlets) of H. heterophyllum were analysed by LC-MS/MS for their chemical contents such as quinic acid, gallic acid, (+)-catechin, ferulic acid, vanillic acid, p-coumaric acid, caffeic acid, and quercetin; moreover their radical scavening activities conducted by DPPH and ABTS methods were evaluated. Among all the analysed samples, the in vitro plantlets shown the highest antioxidant activity (IC50, 220 μg/mL for DPPH and 254 μg/mL for ABTS), probably due to the presence of phenolic acids and flavonoids, specifically the higher total phenolic content (64.4 mg GAE/g extract) than other samples. The phytochemical variation among all samples was discussed through principal component analysis (PCA) and hierarchical cluster analysis (HCA). The in vitro plantlets might offer possibilities for the production of high-value secondary metabolites as pharmaceuticals and food preservatives. This study is the first report on analyses and comparison of secondary metabolites and antioxidant activities in different plant parts and in vitro samples of endemic H. heterophyllum.

Azilsartan Medoxomil

Abstract Five various chemometric methods were established for the simultaneous determination of azilsartan medoxomil (AZM) and chlorthalidone in the presence of azilsartan which is the core impurity of AZM. The full spectrum-based chemometric techniques, namely partial least squares (PLS), principal component regression, and artificial neural networks (ANN), were among the applied methods. Besides, the ANN and PLS were the other two methods that were extended by genetic algorithm procedure (GA-PLS and GA-ANN) as a wavelength selection procedure. The models were developed by applying a multilevel multifactor experimental design. The predictive power of the suggested models was evaluated through a validation set containing nine mixtures with different ratios of the three analytes. For the analysis of Edarbyclor® tablets, all the proposed procedures were applied and the best results were achieved in the case of ANN, GA-ANN, and GA-PLS methods. The findings of the three methods were revealed as the quantitative tool for the analysis of the three components without any intrusion from the co-formulated excipient and without prior separation procedures. Moreover, the GA impact on strengthening the predictive power of ANN- and PLS-based models was also highlighted.

Natural populations of Gentiana asclepiadea L., located at two mountainous sites, were HPLC-analyzed regarding the contents of six representative secondary metabolites. The contents of swertiamarin (SWM), gentiopicrin (GP), sweroside (SWZ), mangiferin (MGF), isoorientin (ISOOR), and isovitexin (ISOV) were determined in six populations (three per study site), and separately for aboveground and belowground plant parts. PCA showed a clear separation of four groups according to the contents of the analyzed secondary metabolites. Out of six analyzed compounds, five were present in all samples and only one (SWZ) was found in Golija populations (belowground parts) but not in Vlasina populations, and its presence can be indicative of the geolocation of populations. Clear separation of groups was mostly affected by the different contents of chemical compounds in plant parts (aboveground versus belowground) and by the differences related to population origin (higher content of SWM and GP in belowground parts of individuals from Vlasina populations and higher content of MGF and ISOOR of individuals from Golija populations). The results of this study contribute to the spatiochemical profiling of G. asclepiadea populations and a better understanding of inter- and intrapopulation variability of pharmacologically important compounds.

AbstractSteroid alkaloid solasodine is a nitrogen analogue of diosgenin and has great importance in the production of steroidal medicines. Solanum erianthum D. Don (Solanaceae) is a good source of solasodine. The aim of this study was to evaluate the effect of different cytokinins on the production of secondary metabolites, especially solasodine in the in vitro culture of S. erianthum. For solasodine estimation, field-grown plant parts and in vitro tissues were extracted thrice and subjected to high-performance liquid Chromatography. Quantitative analysis of different secondary metabolites showed that the amount was higher in the in vitro regenerated plantlets compared to callus and field-grown plants. The present study critically evaluates the effect of the type of cytokinin used in the culture medium on solasodine accumulation in regenerated plants. The highest solasodine content (46.78±3.23 mg g-1) was recorded in leaf extracts of the in vitro grown plantlets in the presence of 6-γ,γ-dimethylallylamino purine in the culture medium and the content was 3.8-fold higher compared to the mother plant.

Oman is endowed with enormous diversity of important food crops that have global significance for food security and has ancient history of cultivation of bread wheat (Triticum aestivum L.) with its divergent landraces, which are useful in crop improvement. 55 indigenous Omani accessions conserved at the USDA were evaluated in the winter season (November to April) of the years 2017-2018 and 2018-2019 on loamy soil under sprinklers in augmented design with 5 check varieties in 5 replications following crop husbandry practices as per national recommendations using 9 quantitative (descriptors) and 6 qualitative traits (anthocyanin pigmentation on plant parts). The data on traits were subjected not only for PC values and D values after varimax rotation through Kaiser normalization in Principal Component Analysis (PCA) but also for Agglomerative Hierarchical Clustering (AHC). The results indicated that indigenous bread wheat accessions were significantly different (p>0.05) for all the quantitative traits except number of tillers. The multivariate analyses led to formation of four diverse clusters from PCA analyses corresponding to four quadrants of bi-plot graphs and three clusters from AHC analysis corresponding to main clades of dendrogram. The parents were selected from common accessions of distinct clusters in all the multivariate analyses for hybridization for improving characters of growth for higher yield or productivity with pigmentation on one or two plant parts useful for DUS test of varieties. The indigenous bread wheat landraces / accessions were genetically diverse and have potential for use in national crop improvement programs for earliness and higher grain productivity with distinct identification markers.

Present study aims to explore the ethnobotanical information on medicinal plants used by Magar community of Badagaun VDC of Gulmi district. The study was carried out during different periods of the year 2010. Informations on plant and plant parts uses were collected interviewing key informants by using semi-structured open-ended questionnaire. Altogether 161 different plant species belonging to 87 familes and 144 genera were documented and majority of them are herbs. In terms of plant parts use, leaf and stem/bark are in top priorities. These plants are used to treat different ailments ranging from gastro-intestinal to headache and fever, respiratory tract related problems to dermatological problems, snake bite to ophthalmic and cuts and wounds. Easy access to modern medicines and less recognition of traditional healers are the main causes leading to decrease in interest of young generation in the use of traditional medicinal practices.
