HMG-CoA reductase converts HMG-CoA to mevalonate,with this catalysis constituting a committed step in the biosynthesis of cholesterol.So,it’s primary drone in treatment coronary artery disease.At present,several statins are available in the drug market,however,up to now the quantitative structure-activity relationship of all of known inhibitors hasn’t been reported.In order to provide a theoretical guide for the synthesis of novel inhibitors,the quantitative structure-activity relationship of the inhibitors of HMG-CoA reductase were performed by using 3D-QSAR approach: comparative molecular field analysis(CoMFA).The computed obtained CoMFA model with(q^2=0.4,) r^2=0.955,SE=0.110,F=85.335.It not only can be used to explain the structure-activity relationship of compound but also has powerful predictive ability. 展开更多

对茶皂甙的提取纯化工艺进行了研究。以含量为70%的粗茶皂甙为原料,经N,N-二甲基甲酰胺溶解、乙酸乙酯沉析、胆甾醇复合吸附、苯解吸工艺得到含量大于99%的茶皂甙,提取率大于80%。结果表明,该工艺为高纯度茶皂甙的制备提供了参考。
