摘要
目的:建立射干抗病毒注射液(射干、金银花、柴胡,等)中野鸢尾黄素的反相高效液相色谱分析方法.方法:色谱柱:Kromasil ODS(5μm,4.6mm×200mm),水-甲醇-乙腈(50:46,4,v/v)以磷酸调pH3.0为流动相,流速0.80mL·min-1,柱温(30.5±1)℃,于265nm测定射干抗病毒注射液中野鸢尾黄素的含量.结果:野鸢尾黄素线性范围:0.0282～9.4μg(r=0.999 9),野鸢尾黄素对照品的进样精密度RSD为1.2%,对照品溶液在18 h内峰面积的RSD为0.72%,检测限(S/N=3)为3.2ng,定量限(S/N=10)为10.6ng,回收率为99.7%.结论:该方法简便、准确、无干扰,可用于测定射干抗病毒注射液中野鸢尾黄素的含量.
AIM: To develope the quantitative analysis approach for irigenin (IRG) in Shegan Kangbingdu Injection(Rhizoma Belamcandae, Flos Lonicerae, Radix Bupleuri, etc.). METHODS: The operation was carried out on the Kromasil ODS column (5 μm, 4.6 mm×200 mm) with the mobile phase comprised of a mixture of water-methanol-acetonitril(50∶46∶5) adjusted pH3.0 by phostrate acid, the flow rate of 0.8 mL·min -1 , the UV detection wavelength at 265 nm and the temperature at (30.5±1) °C . RESULTS: The linear range was in the range of 0.028 2-9.4 μg(r=0.999 9). The relative standard deviations of peak areas for IRG was 1.2% and the standard was stable within 18 h(RSD=0.72%). The LOD (S/N=3) was 3.2 ng, and the limit of quantification (S/N=10) was 10.6 ng and the average recovery was 99.7%. CONCLUSION: The method is simple, rapid and accurate. It can be used for the quality control of Shegan Kangbingbu Injection.
