主　　题：Marsdenia tenacissima Tenacissoside N 

摘      要：A new C21 steroid glycoside,11α-O-tigloyl-12-β-O-acetyl tenacigenin B 3-O-β-D-glucopyranosyl-（1→4）-β-D-glucopyr- anosyl-（1→4）-3-O-methyl-6-deoxy-β-D-allopyranosyl-（1→4）-β-D-oleandropyranoside（1）,named tenacissoside N was isolated from the stems of Marsdenia *** structure of the glycoside was identified by HR-ESI-MS and NMR spectra.
