title: New triterpenoid saponins from the roots of Sinocrassula asclepiadea.
abstract: Five new triterpenoid monodesmosides (sinocrassulosides I-V, 1-5) and six bisdesmosides (sinocrassulosides VI-XI, 6-11), in which 2-11 possess different acyl groups in the glycosidic moieties, were isolated from the roots of Sinocrassula asclepiadea FRANCH. Sinocrassulosides VI (4) and V (5) also contained a novel A-seco aglycone in their structures. All of the structures were determined on the basis of spectroscopic and physicochemical evidence.
