Abstract

Two new benzochromone glycosides, rubrofusarin 6-O-alpha-L-rhamnosyl- (1 --> 6)-O-beta-D-glucopyranoside (1) and demethylflavasperone 10-O-beta-D-glucopyranoside (2), have been isolated from the stem of Berchemia racemosa Sieb. et Zucc. (Rhamnaceae). Their structures were elucidated on the basis of spectroscopic evidence.
