摘要
目的:建立以高效液相色谱(HPLC)法测定不同产地叶下珠中槲皮素含量的方法。方法:色谱柱为ZorbaxSB-C18(250mm×4.6mm,5.0μm),流动相为乙腈-0.2%磷酸(30:70),流速为1mL·min-1,紫外检测波长为370nm。结果:槲皮素进样量在0.05~0.40μg范围内与峰面积积分值呈良好的线性关系(r=0.9999);平均回收率为102.23%,RSD=1.87%(n=6)。云南产的叶下珠中槲皮素的含量最高。结论:本方法简便、快速、准确,可为正确选择叶下珠原料及其综合开发提供科学依据。
OBJECTIVE:To develop a HPLC method for content determine of quercetin in Phyllanthus urinaria from different habitats.METHODS:The determination was performed on Zorbax SB-C18(250 mm×4.6 mm,5.0 μm) column with acetonitrile-0.2% phosphoric acid(30:70) as mobile phase at flow rate of 1 mL·min-1.The detection wavelength was set at 370 nm.RESULTS:The linear range of quercetin was 0.05~0.40 μg(r=0.999 9) with an average recovery of 102.23%(RSD=1.87%,n=6).CONCLUSION:The method is simple,rapid and accurate.It provides scientific basis for the selection of raw material and comprehensive development of P.urinaria.
