摘要
目的:建立除湿止痒软膏中蛇床子素的含量测定方法。方法:采用高效液相色谱法,色谱柱为Agilent TC-C18柱(250mm×4.6mm,5μm),以乙腈∶水(65∶35)为流动相,流速为1mL.min-1,检测波长为322nm。结果:蛇床子素在0.1282-0.7692μg范围内与峰面积呈良好的线性关系,m=0.0005S+0.0009(r=1);平均回收率为100.00%,RSD为0.15%,n=6。结论:该方法简便、可靠、准确,专属性强,可用于该制剂的质量控制。
Objective : To establish a method for determination of osthole in Chunshizhiyang ointment. Methods:Samples were analyzed on an Agilent TC--C18 column (2250mm×4.6mm,5μm)using acetonitrile-water ( 65 : 35 ) as mobile phase. Speed of flow- was 1.0mL· min^-1 and examination wave length was 322nm. Results: Osthole showed a good linearity in the range of 0.1282-0.7692 μ g, regression equation was m=0.0005S+0.0009 (r=l)and tile average recovery was 100.00% (RSD=0.15%, n=6 ). Conclusion : The established methods are simple, accurate, reliable and can be used for the quality control of Chushizhiyang ointment.
