New steroids from Solenostemma argel leaves.
Two new pregnane ester glycosides, named stemmoside A (1) and stemmoside B (2) and a third new polyhydroxy pregnane, named stemmin C (3), were isolated from Solenostemma argel leaves. The structures were achieved by extensive one- and two-dimensional NMR and MS spectroscopic analysis.
