摘要
目的:建立高效液相色谱法,测定热毒清锭中延胡索乙素的含量。方法:色谱柱为AgilentHypersilODS柱(4.0×250mm,5μm),以甲醇-0.1%磷酸溶液(用三乙胺调节pH至6.0)(60∶40)为流动相,检测波长282nm。结果:延胡索乙素在2~10μg范围内呈良好的线性关系(r=0.9999,n=5),平均回收率99.7%,RSD=2.78%(n=5)。结论:本法简便,准确,灵敏度高。
Objective:To establish a method for determination of Tetrahydropalmatine in Reduqing Pastille by HPLC. Methods:The analysis was carried on a column of ODS-C18 (4.0 × 250mm, 5μm)with a mobile phase of methanol-0. 1% phosphate acid(adjusted to pH6.0 by triethylamine) (60 : 40),and the UV detection wavelength was 282nm. Results:The linear relationof Tetrahydropalmatine was excellent within the range of 2-10μg(r=O. 9999,n=5),and the mean recovery was 99.7% with RSD= 2. 78% (n = 5). Conclusion :The method is simple ,accurate ,and highly sensitive.
