摘要: 目的: 建立高效液相电喷雾质谱法对临床常用药物全天麻胶囊中的有效成分天麻素的含量进行测定。 方法: 采用Kromasil C18柱(150 mm×2.00 mm,3.5 μm) 为分析柱,在乙腈和氯化铵水溶液的混合流动相系统中,进行选择性负离子检测,m/z 为 321.00,进样量 10 μL。 结果: 天麻素浓度在 0.05~2.00 μg/mL 范围内具有良好的线性关系(r= 0.9990),平均加样回收率 97.76%(RSD为 1.44%)。 结论: 本法结果准确,操作简便,适合用于全天麻胶囊的质量控制分析检验,是将质谱技术应用于临床常用药物有效成分鉴定和质控的积极尝试。

Abstract: AIM: To establish a liquid chromatography-electrospray ionization mass spectrometry (LC-ESI-MS) method for determination the effective components in Quan Tianma capsule. METHODS: A Kromasil C18 column (150 mm×2.00 mm, 3.5 μm) was used as the analytical column,while a mixture of acetonitrile and ammonium chloride solution was used as the mobile phase.The molecules [M+Cl] - at m/z 321 was used, and the injection volume was 10 μL. RESULTS: There was a good linear relationship in the range of 0.05- 2.00 μg/mL for gastrodin (r=0.9990) , the average recovery rate was 97.76%(RSD was 1.44%). CONCLUSION: The method is accurate, convenient, and can be used for the quantitative analysis of Tianma capsule. Mass spectrogram technology will be used for the effective components identification and quality control of the commonly used drugs in clinic.
