摘要
该实验利用人脐静脉内皮细胞氧化损伤实验、家兔体外凝血4项实验和大鼠心肌缺血实验相结合的方法比较了丹酚酸组分中3个代表性成分的药效活性的差异,并利用CRITIC权重法评价代表性成分的药效贡献率;结果得到丹酚酸组分中代表性成分丹酚酸B、迷迭香酸、丹参素的贡献率分别为28.85%,30.11%,41.04%。采用摇瓶法测定了丹酚酸组分在水以及不同p H缓冲液中的油水分配系数,进一步以质量权重系数和药效贡献率相结合的方法整合表征了该组分整体的油水分配系数,结果表明丹酚酸组分在正辛醇-水/p H 1.2的盐酸溶液/p H 2.0,2.5,5.0,5.8,6.8,7.4,7.8的磷酸盐缓冲液中表观油水分配系数0.32,1.06,0.89,0.98,0.90,0.13,0.02,0.20,0.56。该实验为组分整体性质的表征提供了一定的参考。
The difference between three representative components of total salvianolic acids in pharmacodynamic activity were com- pared by three different pharmacological experiments ： HUVECs oxidative damage experiment, 4 items of blood coagulation in vitro ex- periment in rabbits and experimental myocardial ischemia in rats. And the effects of contribution rate of each component were calculated by multi index comprehensive evaluation method based on CRITIC weights. The contribution rates of salvianolic acid B, rosmarinic acid and Danshensu were 28.85%, 30. 11%, 41.04%. Apparent oil/water partition coefficient of each representative components of total salvianolic acids in n-octyl alcohol-buffer was tested and the total salvianolic acid components were characterized based on a combina- tion of the approach of self-defined weighting coefficient with effects of contribution rate. Apparent oil/water partition coefficient of total salvianolic acids was 0. 32,1.06,0. 89,0. 98,0. 90,0. 13,0.02,0. 20,0. 56 when in octanol-water/pH 1.2 dilute hydrochloric acid so- lution/ pH 2.0,2. 5,5.0,5.8,6. 8,7.4,7.8 phosphate buffer solution. It provides a certain reference for the characterization of compo- nents.
