Congress Abstract

Purgins II and III (1 and 2), glycolipid ester-type dimers, along with purginosides III-IV (3 and 4) were isolated from the chloroform-soluble extracts of the aerial parts of Ipomoea purga. They were purified by preparative-scale recycling HPLC. Compounds 1 and 2 are the first dimers isolated from the morning glory family (Convolvulaceae) containing operculinic acid B as their oligosaccharide cores (monomeric units A and B).
