## Abstract Nine new dammarane saponins, **1**β**9**, were isolated from the MeOH extract of the aerial part of __Gynostemma pentaphyllum__, an edible plant of the Cucurbitaceae family, that grows wildly in China. Their structures were elucidated by 1Dβ and 2DβNMR analysis, as well as by chemical d
## Abstract The six new triterpene saponins **1**β**6** with a 21,23βlactone skeleton were isolated from the MeOH extract of the aerial parts of __Gynostemma pentaphyllum.__ Their structures were elucidated by 1Dβ and 2DβNMRβspectra interpretation as well as by chemical degradation.
