Abstract. Three new diglucosides, mulberrosides D, E, and F, were isolated from Morus alba cell cultures and their structures were established by spectroscopy. In the biosynthesis of mulberroside D, a cinnamoylpolyketide-derived cis-oxyresveratrol diglucoside in the cell cultures, the different ratio of 13C-enrichment between two glucose moieties of mulberroside D, revealed by administering [U-13C6]-D-glucose and [1,3-13C2]glycerol to the cell cultures, suggested that two glucosylation steps in the biosynthesis of the glucoside occur with different time courses.
