Two new dammarane-type sapogenins from Gynostemma pentaphyllum

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.
