A new acylated isoflavone glucoside from Pterocarpus santalinus

Abstract

Phytochemical investigation on the constituents of heartwood of Pterocarpus santalinus resulted in the isolation of a new acylated isoflavone glucoside. The structure of the new compound was elucidated on the basis of spectral studies as 4',5-dihydroxy-7-O-methyl isoflavone 3'-O-β-D-(3'-E-cinnamoyl)glucoside.
