[摘要] 目的 建立感冒热毒清合剂中连翘苷的高效液相色谱(HPLC)法含量测定方法。 方法 对处方中连翘进行定性鉴别,并对连翘苷进行HPLC法测定,采用色谱柱资生堂SHISEIDO CAPCELL PAK MG-C18柱(4.6 mm × 250 mm,5 μm),流动相乙腈-水(76∶24),流速1.0 mL/min,柱温30℃,检测波长277 nm。 结果 连翘苷在6.88~137.6 μg/mL范围内呈良好的线性关系(r = 0.9992),连翘苷的平均回收率为99.20%、99.96%、98.73%。 结论 本文首次建立了感冒热毒清合剂中连翘苷的HPLC含量测定方法,结果准确,重复性好,可作为感冒热毒清合剂的质量评价方法。

[Abstract] Objective To establish a method on content determination of phillyrin in Ganmao-reduqing Mixture by high performance liquid chromatography (HPLC). Methods Phillyrin was performed qualitative identification. The content of phillyrin in mixture was determined by HPLC with a SHISEIDO CAPCELL PAK MG-C18 column (4.6 mm × 250 mm, 5 μm), acetonitrile-water (76∶24) was used as mobile phase and the flow rate was 1.0 mL/min. The columm temperature was set at 30℃ and the wavelength of the detector was set at 277 nm. Results The linear range for phillyrin was 6.88-137.6 μg/mL and the correlation cofficient was 0.9992. The average recovery of phillyrin was 99.20%, 99.96%, 98.73% respectively. Conclusion This is the first time to establish a method using HPLC for determination of phillyrin in Ganmao-reduqing Mixture. The method is accurate, reproducible and suitable to be used for quality assessment of Ganmao-reduqing Mixture.

感冒热毒清合剂(南制字2011F19001)是解放军第一一七医院结合长年的临床实践,并进行处方筛选而研制成的适合临床、治疗感冒效果好、质量稳定的纯中药制剂。该合剂由连翘、板蓝根、金银花等组成,连翘具有清热解毒、消肿散结、疏散风热;用于痈疽,瘰疬,乳痈,丹毒,风热感冒,温病初期,温热入营,高热烦渴,神昏发斑,热淋涩痛[1-2]。连翘苷为连翘中主要成分之一,现代药理学和临床研究表明连翘中的连翘苷具有抗菌、抗病毒、强心、抑制毛细血管通透性、抗肝损伤等作用[3]。感冒热毒清合剂质量标准中有性状、鉴别、检查等检验项目,但没有建立组方中主要成分的含量测定方法,随着中药制剂的发展,对中药制剂的质量提出了更高要求[4-7]。本文选取连翘苷为指标成分,连翘苷为连翘中的主要成分,建立高效液相色谱法含量测定方法[2,8-16],该方法稳定性及重复性较好,测定结果准确可靠,可作为医院制剂-感冒热毒清合剂的质量控制方法。……
