Pharmacognostic, Phytochemical and Physicochemical Investigation of Pueraria tuberosa (Roxb. ex Willd.) DC. Tuber

The present investigation was carried to determine the pharmacognostic characters and the presence of different phytochemical compounds of Pueraria tuberosa tuber. Phytochemical analysis of tuber was carried out by using series of solvents such as petroleum ether, chloroform, ethanol and acetic acid by soxhlet extractor. Qualitative phytochemical analysis showed the presence of carbohydrates, glycosides, tannins and phenolic compound, flavonoids, steroid, triterpenoids, alkaloid, proteins, amino acids, gums and mucilage, etc. Physicochemical parameters such as total ash, acid insoluble ash, water soluble ash, extractive value and moisture content were determined. Qualitative phytochemical and physicochemical analysis is essential for standardization and in determination of medicinal value of crude drugs.
