摘要: 建立大黄灵脾颗粒中淫羊藿苷含量的HPLC测定方法。取2.0 g样品,以25 mL 50%乙醇超声提取30 min,过滤后测定。采用Apollo C18(4.6 mm×250 mm,5 μm)色谱柱,以乙腈-水(28:72)为流动相,流速1.0 mL/min,柱温30 ℃,检测波长270 nm。淫羊藿苷线性范围为0.03836~7.672 μg,回归方程是Y=1271 X+31.68(r=0.9998),精密度、稳定性和重复性试验RSD均小于1.0%,低、中、高浓度平均加样回收率分别为98.63%、98.95%和97.86%,RSD分别为2.0%、0.5%和3.2%(n=3)。该方法简便,快速,重复性好;可用于大黄灵脾颗粒的质量控制。

Abstract: To establish a HPLC method for the determination of icariin in Dahuanglingpi granule.2.0 g sample was ultrasonically extracted for 30 minutes in 25 mL 50% ethanol and determined after filtration.The separation was performed on an Apollo C18 analytical column (4.6×250 mm,5.0 μm) with mobile phase consisting of acetonitrile-water (28:72) at the flow rate of 1.0 mL/min.The detection wavelength was set at 270 nm and the column temperature was kept at 30 ℃.The linear range of icariin was 0.03836-7.672 μg,the regression equation was Y=1271X+31.68 (r=0.9998) and the recovery at 80%,100% and 120% concentration level was 98.63%,98.95% and 97.86% (RSD was 2.0%,0.5% and 3.2%,respectively, n=3).RSDs of precision,stability and reproducibility tests were less than 1.0%.The developed HPLC method was accurate,simple and suitable for the determination of icariin in Dahuanglingpi granule.

Key words: Dahuanglingpi granule, icariin, high performance liquid chromatography
