Jf. Cui et al., Gynostemma pentaphyllum: identification of major sapogenins and differentiation from Panax species, EUR J PH SC, 8(3), 1999, pp. 187-191
Four main dammarane-type aglycones of gypenosides, extracted from the aeria
l parts of Gynostemma pentaphyllum were identified by gas chromatography-ma
ss spectrometry. By detecting these aglycones as well as the aglycones of g
insenosides, a difference in sapogenin composition between Gynostemma penta
phyllum and Panax species was observed, which can be used in the differenti
ation of these plant drugs. (C) 1999 Elsevier Science B.V. All rights reser
