摘要: 目的 建立HPLC法测定甘地胶囊中马钱苷的含量。 方法 色谱柱为Waters Symmtry C18柱(4.6 mm×150 mm,5 μm);流动相为乙腈-水(13∶87);流速1.0 ml/min;检测波长240 nm。 结果 马钱苷对照品在0.030 1~3.01 μg范围内呈良好的线性关系(r=0.999 9),平均加样回收率为99.62%,RSD为0.86%。 结论 本方法简便、准确,重复性好,可用于甘地胶囊中马钱苷的含量测定。Abstract: Objective To establish a HPLC method for the assay of loganin in Gandi capsules. Methods The Waters Symmtry column C18 (4.6 mm×150 mm, 5 μm) was used with acetonitrile-water (13:87) as mobile phase. The flow rate was 1.0 ml/min and the detection wavelength at 240 nm. Results The calibration curves were linear within the range of 0.030 1-3.01 μg (r=0.999 9) for loganin. The average recovery and relative standard deviation of loganin were 99.62% and 0.86%. Conclusion This method is simple, practicable, accurate and fast. It can be used to assay loganin in Gandi capsules.
