Sequential glucosylation determined by NMR in the biosynthesis of mulberroside D, a cis-oxyresveratrol diglucoside, in Morus alba L. cell cultures
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 th
