摘要
目的:建立翻白草中山奈酚、槲皮素含量的高效液相色谱测定方法;方法:采用D iamonsilTMC18柱(4.6mm×150 mm,5μm),以M eOH-0.3%H3PO4(4:6,t/v)为流动相,365 nm波长,流速为1.0 mL.m in-1;结果:待测组分与其它组分分离良好(R>1.5),2组分平均回收率分别为99.2%,RSD=0.6%;99.1%,RSD=2.4%;结论:该方法操作简单、易行,重现性好,可为该原料药及制剂的质控提供参考。
Aim in Herba Potentillae Employing the method of RP - HPLC to determine the content of Kaempferol and quercetin iscoloris. Method: with a column DiamonsilTMC18(4.6mm × 150 mm,5μm)and a mobile phase of MeOH -0.3%, H3PO4(4:6,t/v), the detection wavelength being 365 nm, velocity of flow being 1.0 mL min^- 1. Conclusion: Nice effect of separation is obtained( R 〉 1. 5), the average rate of recovery respectively being 98.9%, 96.2%, and the RSD respectively being 1.62%, 1. 76. It's a simple and reliable way that may provide the reference for the quality control of this raw material medicine and preparation
