Fund Project: This work was financially supported by E&T Modern Center for Natural Products of Liaoning Province of China (No.2008402021).We are grateful to the Analytical Center of Shenyang Pharmaceutical University for the identification of the measurements of NMR, IR, HR-TOF-MS.

Two new sapogenins, named (20S, 24R)-3β, 20, 21β, 25-tetrahydroxy-21, 24-cyclodammarane (1) and 3β-hydroxyetio-17β-dammaranic acid (2), were isolated from the alkaline hydrolysate of Gynostemma pentaphyllum saponins. Their structures were elucidated by spectroscopic methods.
- Gynostemma pentaphyllum,
- Sapogenin,
