摘要
目的:建立测定旋覆花药材中旋覆花素和去乙酰旋覆花素含量的方法。方法:采用高效液相色谱法。色谱柱为Zorbax SB-C18,流动相为乙腈-水(梯度洗脱),流速为1.0 ml/min,柱温为25℃,检测波长为210 nm,进样量为10μl。结果:旋覆花素和去乙酰旋覆花素的检测质量浓度线性范围分别为0.0002-0.005、0.0001-0.0017μg/ml(r=0.9998、0.9994);精密度、稳定性、重复性试验的RSD〈2%;加样回收率分别为99.63%-103.56%、95.98%-101.21%,RSD分别为1.26%、1.84%(n=9)。结论:该方法操作简便,结果准确、可靠,可用于评价旋覆花药材的质量。
OBJECTIVE: To establish a method of simultaneous determination of inulicin and deacetylinulicin in Inulae Flos. METHODS: HPLC was performed on the column of Zorbax SB-C18 with mobile phase of acetonitrile-water(gradient elution)at a flow rate of 1.0 ml/min, the column temperature was 25 ℃, the detection wavelength was 210 nm, and the injection volume was 10 μl. RESULTS: The linear range was 0.000 2-0.005 μg/ml(r=0.999 8) for inulicin and 0.000 1-0.001 7 μg/ml (r=0.999 4) for deacetylinulicin; RSDs of precision, stability and reproducibility tests were lower than 2.0% ; recoveries were 99.63%-103.56% (RSD= 1.26%, n=9) and 95.98 %-101.21% (RSD= 1.84%, n=9), respectively. CONCLUSIONS: The method is simple, accurate and reliable, and can be used for the quality evaluation of Inulae Flos.
