title: Studies on the chemical constituents of Phyllanthus emblica.
abstract: Phytochemical investigations on Phyllanthus emblica have resulted in the isolation of the two new flavonoids, kaempferol-3-O-alpha-L-(6''-methyl)-rhamnopyranoside (1) and kaempferol-3-O-alpha-L-(6''-ethyl)-rhamnopyranoside (2). Their structures were determined on the basis of extensive spectroscopic studies including 2D-NMR experiments.
