摘要
目的:建立以高效液相色谱法同时测定黄连解毒汤中黄芩苷、盐酸小檗碱、栀子苷含量的方法。方法:色谱柱为岛津Sim-packVP-ODSC18(250mm×4.6mm,5μm),流动相为乙腈-0.05%磷酸二氢钾+0.05%三乙醇胺溶液(磷酸调pH3.0,梯度洗脱),检测波长为254nm。结果:栀子苷、盐酸小檗碱、黄芩苷的检测浓度分别在0.4~2.0mg.mL-1(r=0.9981)、0.020~0.40mg.mL-1(r=0.9920)、0.020~0.40mg.mL-1(r=0.9963)范围内与各自峰面积积分值呈良好的线性关系;三者加样回收率分别为99.8%、97.5%、98.1%,RSD分别为1.8%、2.5%、1.5%(n均=6)。结论:本方法专属性强、灵敏度高、操作简便,适用于黄连解毒汤类制剂的质量控制。
OBJECTIVE: To establish an HPLC method for the determination of the contents of baicalin, berberine hydrochloride and jasminoidin in Coptidis decoction for detoxification. METHODS: The samples were separated on Shimazu Sim -pack VP -ODS C18(250 mm × 4.6 mm, 5μm) with mobile phase consisted of acetonitrile - (0.05% potassium dihydrogen phosphate + 0.05% trolamine solution, with pH adjusted to 3.0 by phosphoric acid) in gradient elution under a detection wavelength of 254 nm.RESULTS: The linear ranges of jasminoidin, berberine hydrochloride and baicalin were 0.4-2.0 mg · mL^-1(r = 0. 998 1), 0.020-0.40 mg·mL 1( r = 0. 992 0) and 0.020- 0.40 mg · mL^-1(r = 0. 996 3), respectively, and their average recoveries were 99.8%, 97.5 % and 98.1%, respectively, with RSD at 1.8 %, 2.5 % and 1.5 %, respectively( n = 6 for all the three).CONCLUSION: The established method is specific, sensitive, simple and applicable for the quality control of Coptidis decoction for detoxification.
