Abstract:

Xiaoaiping injection is a single-prescription of Marsdenia tenacissima. One newcompound, tenacigenoside L(1), along with ten known compounds were isolated from the CHCl3-soluble fraction of Xiaoaiping injection extractby silica gel, ODS, Sephadex LH-20 and semi-preparative HPLC chromatography. The new compound was characterized as 3-O-β-D-oleandropyranosyl-17β-tenacigenin B. The ten known compounds were identified as tenacigenin B (2), 17β-tenacigenin B (3), marsdenoside F (4), tenacissoside G (5),tenacissoside I(6), tenacissoside H (7), marsdenoside D(8), tenacigenin A (9), marsdenoside I (10), and tenacigenin C (11). The structures of 11 compounds were elucidated on the basis of extensive analyses of spectroscopic data including MS, 1D NMR and 2D NMR, and comparison of their spectroscopic data with those reported in the literatures.

Key words: Xiaoaiping injection, Marsdenia tenacissima, Polyoxypregnane glycoside
