The crude drug powder extracts from three plants Datura metel L., (Solanaceae), Leucas cephalotes (Roth.). Spreng, Piper betel L., (Piperaceae) were screened for estimating phytochemical constituents. Phytochemical analysis of the extracts revealed that glycoside; tannin, saponin, carbohydrate and phenolic compounds are present in Piper and Leucas species. Besides glycoside, tannin, saponin, carbohydrate and phenolic compound, alkaloid is also present in Datura species.
