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 <i>Sinocrassula asclepiadea</i> F<small>RANCH</small>. Sinocrassulosides VI (4) and V (5) also contained a novel A-<i>seco</i> aglycone in their structures. All of the structures were determined on the basis of spectroscopic and physicochemical evidence.
