title: Gynostemma pentaphyllum: identification of major sapogenins and differentiation from Panax species.
abstract: Four main dammarane-type aglycones of gypenosides, extracted from the aerial parts of Gynostemma pentaphyllum were identified by gas chromatography-mass spectrometry. By detecting these aglycones as well as the aglycones of ginsenosides, a difference in sapogenin composition between Gynostemma pentaphyllum and Panax species was observed, which can be used in the differentiation of these plant drugs.
