摘　　要：中药白薇品种比较混乱,据谢宗万等考证,正品白薇应为萝藦科植物直立白薇(Cynanchum atratum Bunge)和蔓生白薇(C.versicolor Bunge)的根。张壮鑫等报道了直立白薇的C_(21)甾体成分,本文报道蔓生白薇的化学成分。A new C-21 steroidal glycoside named neocynaversicoside (Ⅰ) along with a known compound glaucoside-H was isolated from one of the plant species used as 'Bai-Wei' in traditional Chinese medicine, Cynanchum versicolor Bunge, and its structure was deduced as neocynapanogenin 3-O-β-D-thevetopyranoside on the basis of chemical and spectral evidence.
