摘要: 采用液质联用(HPLC-ESI-MSn)技术, 对不同pH值(2.4~11.2)条件下人参皂苷的溶出变化规律进行了系统研究, 并提出了不同人参皂苷化合物的特征质谱裂解规律. 实验结果表明, 中性及碱性溶液对人参皂苷的溶出影响不大, 仅仅在溶出总量上有所差别; 而酸性是影响人参皂苷溶出的一个主要因素, 随着水溶液酸性的增强(pH<4), 人参皂苷溶出的种类明显减少, 表明较强酸性条件下人参皂苷的溶出受到了抑制.

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
