目的:建立测定枳壳药材中川陈皮素、红橘素的HPLC定量分析方法。方法:采用Venusil XBP C18色谱柱(4.6mm×150mm,5μm),以乙腈-水(45∶55)为流动相,流速1.0mL·min-1,检测波长326nm,柱温25℃。结果:川陈皮素、红橘素进样量分别在0.16~3.11μg和0.12~2.34μg范围内色谱响应线性关系良好,相关系数均为0.9999;平均回收率(n=5)分别为97.9%和99.7%,RSD值分别为1.1%和0.44%。结论:本法简便、准确、可靠,可作为枳壳药材中川陈皮素与红橘素含量测定的有效方法。
Objective : To establish a method for the quantification of nobiletin and tangeretin in Fructus Aurantii by HPLC. Methods:The Venusil XBP Clscolumn(4. 6 mm × 150 mm,5 μm)was adopted with the mobile phase of acetonitrile -water(45: 55)at 25 ℃;The flow rate was 1.0 mL ·min-1, and the detection wavelength was 326 nm. Results :The method had good linear relationship within the range of 0. 16 -3.11 μg( r = 0. 9999)for nobiletin and 0. 12 - 2. 34 μg ( r = 0. 9999 ) for tangeretin. The average recoveries ( n = 5 ) were 97.9% ( RSD = 1.1% ) for nobiletin and 99.7% ( RSD = 0. 44% ) for tangeretin. Conclusion : This method is convenient, accurate and reliable for the quantification of nobiletin and tangeretin in Fructus Aurantii.
