摘要:

应用超高效液相色谱-四极杆-静电场轨道阱串联质谱(UPLC-Q-Orbitrap MS/MS)联用技术分析鉴别人参发酵前后的皂苷类化合物, 研究了整体人参皂苷在自然发酵过程中的生物转化规律. 通过鉴定45种人参皂苷, 比较了生晒参和发酵人参中人参皂苷种类及含量的差异, 在发酵人参中检测到20(S)-Rg3和20(R)-Rg3, 20(S)-Rh1和20(R)-Rh1等异构体人参皂苷, 其中10余种人参皂苷在自然人参状态下不存在或未被检出. 本研究对于人参发酵前后的化学成分变化进行了高通量的精准分析, 对同类天然产物发酵研究具有借鉴意义, 可指导人参炮制品生晒参和发酵人参的安全有效使用.

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
