ABSTRACT
Objective To establish a method for the isolation and characterization of gypenosides from Gynostemma pentaphyllum. Methods Gypenosides were isolated with chromatography using silica gel and reversed semi-preparative HPLC and identified with 1H-nuclear magnetic resonance spectrum, 13C- nuclear magnetic resonance spectrum and liquid chromatography-ion trap time of flight tandem mass spectrometry. Results The two constituents isolated from Gynostemma pentaphyllum were identified as dammarane-type saponins, gypenoside XLVI and gypenoside LVI, respectively. Conclusion Ggypenosides can be isolated effectively by silica gel chromatography and reversed semi-preparative HPLC.
