摘要: 目的: 建立HPLC法测定复方杜仲丸中盐酸水苏碱与黄芩苷的含量。方法:采用高效液相色谱(HPLC)法,强阳离子交换(SCX)色谱柱测定盐酸水苏碱的含量,十八烷基硅烷键合硅胶测定黄芩苷的含量。结果:盐酸水苏碱在0.01012~1.012 mg?mL-1、黄芩苷在0.00501~0.501 mg?mL-1浓度与峰面积具有良好的线性关系(r值均为0.9998);盐酸水苏碱与黄芩苷回收率均符合要求。结论:该方法可控制复方杜仲丸中益母草与黄芩的含量。
Abstract: Objective: Establishment of a HPLC method for the determination of the contents of hydrochloric acid and baicalin in fufang duzhong pill. Methods:HPLC was used to determine the content of Stachydrine Hydrochloride with (SCX) column;HPLC was used to determine the content of baicalin with ODS column. Results: The Stachydrine Hydrochloride linear ranges were 0.01012~1.012 mg?mL-1 and Baicalin in the range of 0.00501~0.501 mg?mL-1. The recovery results were according to the requirement(r=0.9998). Conclusion:The HPLC method can be used for the quality control of fufang duzhong pill.
