Abstract
目的建立以HPLC法同时测定利胆排石片中木香烃内酯和去氢木香内酯含量的方法。方法色谱柱:依利特SinoChrom ODS-BP柱(4.6 mm×200 mm,5μm),流动相:乙腈-水(体积比为65∶35),流速:1.0 mL.min-1,检测波长:225 nm,柱温:室温。结果木香烃内酯和去氢木香内酯的质量浓度分别在6.160~123.200 mg.L-1和4.600~92.000 mg.L-1内与峰面积呈良好的线性关系,相关系数分别0.999 7和0.999 6;平均回收率分别为100.6%和99.9%,RSD分别为1.0%和0.9%。结论本方法可作为利胆排石片的质量控制方法之一。
