摘要
目的:建立用HPLC法测定乌药中异乌药内酯含量的方法。方法:色谱柱为Kromasil C18柱(250mm×4.6mm,5um),流动相:甲醇-乙腈-水(35:25:40,v/v);检测波长:235nm;柱温:40℃;流速:1mL/min。结果:异乌药内酯的进样量在0.15μg~1.52μg(r=-0.9997,n=6)的范围内与峰面积呈良好的线性关系;平均回收率为98.81%,RSD为1.52%。结论:该法简单、可靠,可作为控制乌药药材质量的参考标准。
Objective: To establish a method for determination of isolinderalactone in Radix linderae by RP-HPLC. Method: The sample was separated on Kromasil C18 (250 mm×4.6 mm,5μm) column, the mobile phase was ethanol-acetonitrile-water (35:25:40v/v) at a flow rate of 1.0 mLomin-1 and the detection wavelength was 235 nm and the column temperature was 40℃. Results: The calibration carves were linear in the range of 0.15μg~1.52μg (r=0.9997,n=6). The average recoveries of isolinderalactone were98.81%, RSD were 1.52%. Conclusion: The method is simple, accurate, reproducible and can offer referenees for the quality control of Radix linderae.
