摘要 目的:建立染料木素自微乳中染料木素含量的HPLC测定方法。方法:采用Diamonsil C18色谱柱(150mm×4.6mm,5μm),甲醇-0.05%磷酸(60:40)为流动相,流速1.0mL·min^-1,检测波长260nm,柱温为25℃。结果:染料木素在1.18-11.8mg·L^-1范围内与峰面积呈良好的线性关系(r=0.9998),平均回收率为99.27%,RSD为1.40%。结论:该方法操作简便、结果准确、重现性好,可用于染料木素自微乳的质量控制。 Objective :To establish a HPLC method for the determination of genistein in genistein self- microemulsifying system. Methods : Diamonsil C18 column ( 150mm × 4.6mm ,5μm)was used with a mobile phase of methanol -0.05 % phosphoric acid(60:40) and the flow rate was 1.0mL · min^-1 ,the detection wavelength was at 260nm and temperature at 25 ℃. Results : Genistein presented a good linear correlation in the range of 1.18 - 11.8mg · L^-1 ( r = 0.9998). The average recovery was 99.27% and RSD was 1.40%. Conclusion :The method is convenient,accurate and reproducible. It can be used for quality control of this preparation.
