摘要
目的:建立以高效液相色谱法测定小儿止咳颗粒中黄芩苷含量的方法。方法:色谱柱为YWGC18(150mm×4.6mm,μm),10流动相为甲醇-水-磷酸(47∶53∶0.2),流速为2.5mL·min-1,检测波长为280nm,进样量为10μL。结果:黄芩苷的检测浓度在25~200μg·mL-1范围内与峰面积积分值呈良好线性关系(r=0.9996);平均回收率为99.57%,RSD=1.91%(n=6)。结论:本方法灵敏、简便、准确,可用于小儿止咳颗粒的质量控制。
OBJECTIVE: To establish the HPLC method for the content determination of baicalin in Xiaoer zhike granule. METHODS: YWG C18 (150 mm×4.6 mm,10 μm) column was used and the mobile phase consisted of methnol-water-phosphoric acid (47 ∶ 53 ∶ 0.2) with the flow rate of 2.5 mL·min-1. The detection wavelength was set at 280 nm and injection volume was 10 μL. RESULTS: The linear range of baicalin was 25~200 μg·mL-1(r=0.999 6) with an average recovery of 99.57%(RSD=1.9%,n=6). CONCLUSION: This method is sensitive, simple and accurate for the quality control of Xiaoer zhike granule.
