【 摘 要 】

Objective: To evaluate the pharmacognostic properties, including the macroscopic,microscopic, physicochemical characteristics and phytochemical screening of the leaves ofWedelia trilobata (W.trilobata) Methods: Microscopic and macroscopic characteristics offresh and dried leaf samples were analyzed. Organoleptic evaluations and physicochemicalstudies were performed using WHO-recommended parameters, and fluorescence behavior ofthe leaf sampleswas also analyzed. serial exhaustive extraction was done with various ofsolvents: Aqueous, Chloroforms, Ethanol, Methanol, Acetone, Benzene, Petroleum ether withincreasing polarity using soxhlet apparatus. The phytochemical analysis was done by using thestandard procedure. Results: Microscopic studies revealed the presence of three-lobate leaves,with the arrangements of spongy and palisade tissues. Physicochemical parameters such asforeign matter, moisture content, extractive values, ash content, pH, and fluorescence behaviorof leaf powder were also determined. The results revealed that the leaves extracts containFlavonoids, Terpenoids, Tannins, Phlobatannins, Saponins, Cardiac glycosides, Carbohydrate,Protein and Anthraquinones in major proportion. Conclusions: This is the first report on thepharmacognostic studies of W.trilobata and helpful in the characterization of the crude drug.Further phytochemical research is needed to identity the active product of S. alata may serveas leads in the development of new pharmaceuticals.
