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.

Bathysa cuspidata (A. St. Hil.) Hook. f. ex K. Schum. is a species native to the Atlantic Rainforest of Brazil, with stem bark currently used in folk medicine. Uncontrolled bark collections cause problems of environmental sustainability, making it necessary to evaluate more abundant and renewable new sources of raw plant material, such as leaves. This work evaluated the anatomy, histochemistry and phytochemistry of leaves and stem bark of B. cuspidata, aiming to find similarities in the chemical composition between these plant parts and to provide anatomical data to supplement the quality control of this plant drug. Common light and scanning electron microscopy techniques were used in the anatomical and histochemical studies. Thin-layer chromatography and high-performance liquid chromatography were used for the phytochemistry analysis. The concentration of total phenolics was determined using the Folin–Ciocalteau method and the contents of proanthocyanidins using the vanillin reagent. The leaves and bark of B. cuspidata display morphoanatomical characters common to the family Rubiaceae. The histochemical and phytochemical results reveal similarities and differences between the leaves and bark of B. cuspidata, suggesting that the extracts of both parts should be considered and subjected to pharmacological studies in order to investigate the effectiveness of the therapeutic actions reported in folk medicine.

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.

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.

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.
