Abstract

Abstract: HPLC-ESI-MSⁿ was used for the analyses of the stripping of gingsenosides in values aqueous solutions with different pH(pH=2.4~11.2). Using tandem mass spectrometry, the characteristics fragment ions of ginsenosides were obtained. The experimental results showed that the stripping of ginsenosides were different in aqueous solutions with different pH values. Acidity is a main factor for influencing the stripping of ginsenoside, and the stripping of ginsenosides are inhibitied in a high acidity(pH<4.4).

Key words: HPLC-ESI-MSn, Ginseng, Ginsenoside
