摘要
目的:建立芩连片中连翘苷的含量测定方法。方法:采用高效液相色谱法,色谱柱为Kromasil C18(250mm×4.6mm,5μm),流动相为乙腈-水(25:75,v/v),流速为1.0mL·min^-1,检测波长为277nm。结果:连翘苷在0.375-2.250μg范围内呈良好的线性关系(r=0.9998),平均回收率为97.4%,RSD为1.30%。结论:本方法灵敏、准确、专属性强,可用于芩连片中连翘苷的含量测定。
Objective : To establish a method for determination of phillyrin in Qinlian tablets. Methods : HPLC analysis was carried out on Kromasil C18 column ( 250mm × 4.6mm, 5 μ m ) and the mixture of acetonitrile-water (25 : 75, v/v )was used as the mobile phase, the flow rate was 1.0mL · min^-1 and the detection wavelength was at 277nm. Results : The standard curve was linear within the range of 0.375-2.250 pug ( r = 0.9998 ), the average recovery was 97.4 %, RSD was 1.30%. Conclusion : The method is semitive, accurate, specific and can he used for the determination of nhillvrin in Oinlian tablets.
