Abstract

Two new flavone glycosides were isolated along with diosmetin, luteolin, and luteolin 7-O-glucoside, from the leaves of Cassia torosa CAV., and their structures were established as diosmetin 3'-O-β-D-glucopyranoside (1) and torosaflavone B 3'-O-β-D-glucopyranoside (2) (diosmetin 6-C-β-D-oliopyranosyl-3'-O-β-D-glucopyranoside) on the basis of spectroscopic and chemical evidence.
