Dammarane-Type Glycosides from Gynostemma pentaphyllum

Fifteen new dammarane glycosides (1−15), together with four known compounds, gypenosides IV, VIII, LXXI, and XLIX, were isolated from the MeOH extract of the aerial parts of Gynostemma pentaphyllum. Their structures were elucidated by 1D and 2D NMR spectra interpretation as well as by chemical degra...
