Abstract:
Absidia coerulea transformed four anthraquinones from rhubarb, chrysophanol, physcion, emodin and aloe-emodin to their corresponding glycosylated metabolites. The structures of the products were characterized as chrysophanol 8-O-beta-D-glucoside, physcion 8-O-beta-D-glucoside, emodin 6-O-beta-D-glucoside, and aloe-emodin 1-O-beta-D-glucoside, respectively.
