A pair of new C-21 steroidal glycoside epimers from the roots of Cynanchum paniculatum

J Nat Prod. 2004 Jan;67(1):82-4. doi: 10.1021/np034013c.

Abstract

Two new C-21 steroidal glycoside epimers, paniculatumosides A and B (1 and 2), based on a 13,14:14,15-disecopregnane-type skeleton, with neocynapanogenin B (3) and neocynapanogenin C (4) as two new aglycons, were isolated from the roots of Cynanchum paniculatum. Their structures were determined by spectral data interpretation.
