Ingia / Ingia
To differentiate the sweet and bitter taste variants of a Chinese medicinal tea Gynostemma pentaphyllum (GP), a method for the quantitative analysis of ginsenosides Rb(1), Rb(3), Rd, and F(2) in GP by using UPLC-Q-TOF-MS was developed. According to the different contents of the four ginsenosides,

Dammarane-type glycosides and long chain sesquiterpene glycosides from Gynostemma yixingense.
