摘  要:目的:建立测定口溃散中靛蓝含量的方法。方法:采用高效液相色谱法。色谱柱为Agilent TC-C18(250mm×4.6mm,5μm),流动相为甲醇-水(75:25,刃功,流速为1.0ml/min,检测波长为289nm,柱温为30℃。结果:靛蓝的进样量在O.198~1.188gg范围内与其峰面积积分值呈良好线性关系(r=0.9998);精密度、稳定性、重复性试验的RSD均〈2%;平均加样回收率为99.61%,RSD=0.69%(n=6)。结论:该方法操作简便、准确可靠、专属性强、重复性好,可用于口溃散中靛蓝的含量测定及其质量控制。OBJECTIVE: To establish the method for the content determination of indigo in Koukui powder. METHODS: HPLC was used. The determination was performed on Agilent TC-C18(250 mm×4.6mm,5μm) column with mobile phase consisted of methanol-water(75 : 25, V/V) at the flow rate of 1.0 ml/min. The detection wavelength was set at 289 nm, and the column temper- ature was 30 ℃. RESULTS: The linear range of indigo was 0.198-1.188 μg(r=0.999 8) with an average recovery of 99.61% (RSD=0.69%, n=6). RSDs of precision, stability and reproducibility tests were all lower than 2 %. CONCLUSIONS: The meth- od is simple, accurate, reliable, specific and reproducible for the content determination and quality control of indigo in Koukui powder.
