title: Triterpenoidal saponins from Gleditsia sinensis.
abstract: Six bisdesmosidic triterpenoidal saponins, gleditsiosides H-K and gleditsia saponins C' and E', were isolated from the anomalous fruits of Gleditsia sinensis. Their structures were established by a combination of extensive NMR (DEPT, DQF-COSY, HETCOR, HOHAHA, HMBC and ROESY) studies and chemical degradation.
