Repeated exposure to inhibitory compounds can drive the evolution of resistance, which weakens chemical defence against antagonists. Floral phytochemicals in nectar and pollen have antimicrobial properties that can ameliorate infection in pollinators, but evolved resistance among parasites could diminish the medicinal efficacy of phytochemicals. However, multicompound blends, which occur in nec...

bermudagrass [cynodon dactylon (l.) pers.] is a perennial grass and has been long used as a medicinal herb in iranian traditional medicine to treat varied ailments. different parts of bermudagrass such as leaves, stolons, rhizomes and culms are rich sources of metabolites such as proteins, carbohydrates, mineral constituents, β-sitosterol, flavonoids, alkaloids, glycosides and triterpenoides. g...

Vitex negundo Linn. belong to family Verbenaceae. It is an important medicinal plant. Literature survey of V. negundo revealed the presence of different classes of natural products including essential oil, triterpenes, diterpenes, sesquiterpenes, lignan, flavonoids, flavones glycosides, iridoid glycosides, and stilbene derivative. The plant is traditionally reported for its use for the treatmen...

Sample of Tetracarpidium conophorum root (Nigerian walnut) was analysed for phytochemical composition, Vitamins and Mineral constituents. Phytochemical screening and subsequent quantification revealed the presence of bioactive compounds. Tannin,0.545mg/g Saponin,10.705mg/g, Alkaloid,0.41mg/g, Oxalate,0.895mg/g, Phenols, 0.215mg/g. The mineral analysis revealed K,0.002mg/g, Ca,0.004mg/g, Na,0.00...

objectives this study was designed to determine the chemical composition, in vitro antioxidant activity, and total phenol content of various extracts of s. chloroleuca. materials and methods dried aerial parts of the plant were crushed, then sequentially extracted with n-hexane, ethyl acetate, and methanol. the fractions of s. chloroleuca were subjected to silica gel column chromatography and s...

Standardization is an important step for the establishment of a consistent biological activity, a consistent chemical profile, or simply a quality assurance program for production and manufacturing of herbal drugs preparation of any herbal formulation identification, evaluation and standardization is rudimentary identification involves the morphology, microscopy parameter of plants, evaluation ...

BACKGROUND The use of medicinal plants in Ayurveda is based on rasa, generally taken to represent taste as a sensory perception. This chemosensory parameter plays an important role in Ayurvedic pharmacology. OBJECTIVE The aim is to explore the use of structuro-functional information deduced from analytical techniques for the rasa-based classification of medicinal plants in Ayurveda. MATERIA...

The aim of this study was to establish pharmacognostic profiles of dried leaf powder of Cardiospermum halicacabum Linn. and dried seed hull powder of Hydnocarpus pentandra (Buch.-Ham.) Oken. The present study investigates various qualitative and quantitative parameters like microscopic evaluation of plant powder, physicochemical constants and preliminary phytochemical analysis. Microscopic eval...
