ESTIMATION OF PHYTOCHEMICAL CONSTITUENTS IN THREE PLANTS WIDELY USED FOR TRADITIONAL TREATMENT OF ASTHMA IN MYANMARAbstract
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. The antimicrobial activity of the plant materials and their usefulness in the treatment of asthma may be due to the presence of active constituents like tannins, alkaloids and phenolic. The present study reported that the phytochemical constituents of three plants being widely used for traditional treatment of asthma in Myanmar, collected from Kalay, Sagaing District.
