摘要
目的:建立以反相同效液相色谱法测定毛鱼藤中鱼藤酮含量的方法。方法:以ZORBAX Eclipse XDB—C18(5μm,4.6×150mm)色谱柱为固定相;乙腈:0.1%磷酸溶液(48:52,v/v,pH2.6)为流动相;流速1.0mL/min;柱温40.0℃;检测波长299nm。结果:鱼藤酮在浓度为30~50mg/L范围内,其峰面积与浓度线性关系良好,线性方程为A=20.7311C-0.3616(r=0.9998),平均加样回收率为100.74%,RSD为0.86%。结论:本方法操作简便、快速.结果准确.可用于毛鱼藤中鱼藤酮的含量测定。
Objective:To establish a reversed-phase high performance liquid chromatography method for rotenone in Derris elliptica, Methods :The determination was performed on ZORBAX Eclipse XDB-C18 (5 μm,4.6 × 150 mm)column. The mobile phase consisted of acetonitrile and 0.1% phosphate acid solution (48 :52, v/v, pH 2.6) with flow rate at 1.0 mL/min and determination wavelength at 299 nm under 40.0 %, Results : Under the conditions described, the calibration curve of rotenone was linear over the concentration range of 30 to 50 mg/L. The regression equation was : A = 20.731 1C-0.361 6, r = 0. 999 8 ( n = 5 ,P 〈 0.01 ). The average recovery for rotenone was 100.74%. The mean relative standard deviation (RSD) was 0.86%. Conclusion:The method is simple and accurate, and suitable for the determination of rotenone in Derris elliptica.
