| Abstract: | Objective To study chemcial constituents in the canes of Marsdenia tenacissima.Methods Chemical constituents were isolated and purified by silica gel and ODS column chromatography.The structures were identified by means of physico-chemical and spectral data.Results From the 70%ethanol extract of the material,four compounds were isolated.Their structures were identified as 11α,12β-di-O-2-methylbutyryl-tenacigenin B(Ⅰ),11α-O-2-methylbutyryl-12β-O-acetyl-tenacigenin B(Ⅱ),tenacissoside H(Ⅲ),and marsdenoside A(Ⅳ),respectively.Conclusion Compound Ⅰ is a new C_(21) steroid compound,named tenacissoside O. |
