Abstract

Saponins in leaf and stem of Gynostemma pentaphyllum that was collected from Jeju Island were extracted by the method for ginseng saponin. Comparison by overlapping chromatogram(HPLC) of pentaphyllum on that of ginseng and cochromatogram and ginseng although ginsenoside Rg2, Rg1 and Rf might be in common with rare possibility. It seems to be little difference in the kind of saponin glycosides between leaf and stem of pentaphyllum. Saponin content in leaf of pentaphyllum was higher than in stem, and much higher than those in ginseng. The kind of saponin glycoside in pentaphyllum appeared to be less than 22 and greater than those in ginseng. There was almost no change in saponins of pentaphyllum in methanol for 3 years at room temperature.
