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.
