Abstract:

This work aims to analyze and compare the ginsenosides contents from white ginseng and fermented black ginseng(FBG) using UPLC-Q-Orbitrap MS/MS(ultra performance liquid chromatography coupled with quadrupole orbitrap tandem mass spectrometry). FBG was processed by spontaneous short-term fermentation, along with the biotransformation of ginsenosides. The samples were separated by liquid chromatography using a Thermo Syncronis C18 column at 30 ℃. Moreover, 0.1%(volume fraction) formic acid and acetonitrile were used as mobile phases A and B, respectively. The flow rate was 0.2 mL/min, and the injected sample volume was 0.5 μL. By the use of the UPLC-Q-Orbitrap MS/MS, 52 kinds of ginsenosides were identified. The contents of main ginsenosides, especially in malonylated ginsenosides, were decreased, because of hydrolyzed. The method of spontaneous short-term fermentationdid doesn’t require any additives, and provides the theoretical basis for spontaneous short-term fermentprocessed ginseng.

Key words: Fermentation, Ginsenoside, Biotransformation, Liquid chromatography-mass spectrometer
