摘要
目的:建立以高效液相色谱法测定栀柏合剂中栀子苷含量的方法。方法:色谱柱为Shim-packV-ODSC18(150mm×4.6ram,5μm),流动相为乙腈-水(12:88),流速为lmL·min^-1,检测波长为238nm,柱温为25℃。结果:栀子苷检测浓度在25--100rag·L。范围内与峰面积积分值呈良好线性关系(r=0.9997);平均回收率为99.89%,RSD=0.80%(n=9)。结论:本方法灵敏度高、专属性强、重现性好,可用于本制剂的质量控制。
OBJECTIVE: To establish a HPLC method for the quantitative determination of Geniposide in Zhibo mixture. METHODS: The separation of sample was performed on Shim- pack VP- ODS C18 column(150mm × 4.6mm, 5μm) at a tem- perature of 2512. The mobile phase consisted of acetonitrile- water (12 : 88) at a flow rate of lmL · min^-1. The detection wavelength was set at 238nm. RESULTS: The linear range of Geniposide was 25-100mg · L^-l(r = 0.999 7) . The average recovery was 99.89% (RSD = 0.80%, n = 9). CONCLUSION : The method was proved to be sensitive, specific, reproducible and suitable for quality control of Zhibo mixture.
