Abstract:
:Gynostemma pentaphyllum is a popular functional food, and it is also used as a traditional medicine in Asia. In this study, five previously undescribed triterpenes, gypensapogenin M, gypensapogenin N, gypensapogenin O, gypensapogenin P, and gypensapogenin Q, together with five known compounds were isolated from the hydrolyzate of total G. pentaphyllum saponins. The bioassay data showed that all the triterpenes exhibited significant protective activity against H2O2-induced myocardial cell injury and anti-hepatic fibrosis activity. Taken together, the discovery of these triterpenes from the hydrolyzate of total G. pentaphyllum saponins expands its use as a functional food for preventing myocardial injury and liver fibrosis.
