| Research Abstract |
When a fabatriosyl moeity, the most popular sugar linkage attached to C-3 OH of the leguminous oleanene glycosides, was taken off, the activity of antihepatitis was decreased, therefore, it was supposed that a sugar linkage might contribute to express activity. The fabatriosyl residue was cut off with glycyrrhinic acid hydrolase and subsequently attached to other steroidal sapogenol, diosgenin, to give a new glycoside which was shown to have a strong activity. This method would be one way to approach for disclosing the biological roles of the sugar moiety in molecular level.
