摘  要:利用高效液相色谱-飞行时间质谱联用的方法,分别对人参配伍山楂前后人参皂苷的变化进行分析,同时对人参皂苷Re、Rg1、Rb1、Rd与山楂配伍的水解规律进行系统研究,并与单独煎煮液、仿山楂配伍pH值煎煮液的水解产物进行比较,结果发现人参与山楂配伍后人参皂苷Rg1、Rb1含量明显减少,而人参皂苷Re、Rd、Rg2、Rg3、F2、Rh1含量明显增加,其中人参皂苷Re与山楂配伍后水解产物为人参皂苷20(R)-Rg2、20(S)-Rg2,仿山楂配伍pH值水解产物为人参皂苷20(R)-Rg2、20(S)-Rg2、Rg4、Rg6;人参皂苷Rg1与山楂配伍后水解产物为20(S)-Rh1、20(R)-Rh1,仿山楂pH值水解产物为20(S)-Rh1、20(R)-Rh1、Rh4、Rk3;人参皂苷Rb1与山楂配伍后水解产物为Rd、20(S)-Rg3,仿山楂pH值水解产物为F2、20(S)-Rg3;人参皂苷Rd与山楂配伍后水解产物为F2、20(S)-Rg3、20(R)-Rg3,仿山楂pH值水解产物为20(S)-Rg3、20(R)-Rg3。研究表明,不同人参皂苷和山楂配伍后与仿山楂pH值的水解产物并不相同,人参与山楂配伍改变了人参皂苷成分的种类及含量。本研究为临床方剂中人参与山楂配伍后成分的变化提供物质基础数据。High performance liquid chromatography coupled with quadrupole-time-of-flight tandem mass spectrometry( HPLC-Q-TOF MS/MS) were used for the comparative analysis of the content of ginsenosides in the decoction of Panax ginseng with hawthorn and hydrolysis of ginsenosides in compatibility of ginsenosides Re, Rgl, Rbl, Rd with hawthorn, single decoction and simulated pH value decoction. The results show that the contents of ginsenosides Rgl and Rbl decrease, while the contents of ginsenosides Re, Rd, Rg2, Rg3, F2, Rhl increase in ginseng-hawthorn combined decoction. Ginsenosides 20 (R) -Rg2, 20 (S) -Rg2 are the hydrolysates when ginsenoside Re and hawthorn are boiled together, while others are ginsenosides 20 (R)- Rg2, 20(S)-Rg2, Rg4 and Rg6 when ginsenoside Re is boiled in the same pH value without hawthorn. In addition, the hydrolysates are ginsenosides 20 (S)-Rhl and 20 (R)-Rhl in ginsenoside Rgl-hawthorn combined decoction, but ginsenosides 20(S)-Rh1, 20 (R)-Rhl, Rh4, Rk3 are determined in the simulated pH value decoction. Ginsenosides Rd, 20 (S)-Rg3 are the major hydrolysates in co-decoction of ginsenoside Rbl and hawthorn, while ginsenosides F2, 20 (S)-Rg3 are the major hydrolysates from the simulated pH value decoction. Ginsenosides F2, 20 (R) -Rg3, 20 (S) -Rg3 are hydrolysates in ginsenoside Rd-hawthorn combined decoction, but ginsenosides 20 (R)-Rg3, 20 (S)-Rg3 are hydrolysates in the simulated pH value decoction. The hydrolysis of ginsenosides is different in the processes of co-decoction with hawthorn and the simulated pH value decoction, which may be the basis of chemical composition in combination of Panax ginseng and hawthorn. It provides the material bases for combination of Panax ginseng and hawthorn in prescriptions of traditional Chinese medicine.
