摘要: 目的 建立测定消亢胶囊含量的方法。 方法 采用高效液相色谱(HPLC)法测定消亢胶囊中迷迭香酸的含量。色谱柱:Agilent C18柱,流动相:甲醇-0.5% 甲酸(50:50),流速:1 ml/min,检测波长:330 nm,柱温:30 ℃,进样量:10 μl。 结果 消亢胶囊中夏枯草迷迭香酸的浓度在2.88~20.16 μg范围内与峰面积积分值呈良好的线性关系(r=0.999 8),平均回收率为99.54%,RSD为0.40%(n=9)。 结论 该方法操作简便、结果准确可靠,适用于消亢胶囊中迷迭香酸的含量测定。Abstract: Objective To develop a method for determination of the rosmarinic acid in Xiaokang capsules. Methods An HPLC method was developed. The determination was performed on Agilent C18 column at 30℃ with a mobile phase composed of methanol: 0.5% formic acid (50:50) run at a flow rate of 1.0 ml/min. The detection wavelength was set at 330 nm and the injection volume was 10 μl. Results The linear range of rosmarinic acid concentrations was 2.88 to 20.1 μg/ml (r=0.999 8). The average recovery was 99.5% (RSD=0.40%,r=9). Conclusion An assay for the determination of the rosmarinic acid in Xiaokang capsule that is simple, rapid, accurate and reliable has been developed.
