Isolation of Flavonol of Tephrosia purpurea

摘要

ABSTRACT Flavonoids have been reported as naturally occurring compounds and considered as secondary metabolites responsible for biological activities. The flavonoids are divided into several classes, i.e., anthocyanins, flavonols, flavones, flavanones, dihydro flavonols, chalcones etc. A flavonol, Kaempferol 7-O-(rhamnosyl)glucoside, was isolated from whole plant of Tephrosia purpurea. The isolated compound was identified by melting point, chemical test, IR, NMR and mass spectra. Keywords: Teph.
