摘要
目的 :建立川天康胶囊中阿魏酸和天麻素的含量测定方法。方法 :采用ODS柱 ,流动相分别为甲醇 - 1%冰醋酸(5 0∶5 0 )和甲醇 -磷酸盐缓冲溶液 -水 (4∶4∶92 ) ,检测波长为 313nm和 2 70nm。结果 :阿魏酸对照品在 0 .5 0 8～ 2 .5 4μg之间呈良好的线性关系 ,平均加样回收率为 99.72 %、RSD为 1.0 1%。天麻素对照品在 0 .80 8～ 1.16 1μg之间呈良好的线性关系 ,平均加样回收率为 92 .0 7%、RSD为 1.2 1%。结论
Objective: To establish a method to determine the contents of Ferulic acid and Gastrodin in Chuantiankang Capsules.Methods: HPLC conditions: ODS column, two types of mixtures of methanol 1% glacial acetic acid (50∶50) and methanol phoshate buffer solution water (4∶4∶92) as mobile phases, detection wavelengths were 313nm and 270nm.Results: For Ferulic acid the linear range was 0.508～2.54μg and the average recovery was 99.72% with RSD=1.01%. For Gastrodin the linear range was 0.808～1.161μg and the average recovery was 92.07% with RSD=1.21%. Conclusion: These methods can be used for the quantitative analysis of Chuantiankang Capsules.
