摘要
目的:建立反相高效液相色谱法测定复方金银花颗粒中黄芩苷含量的方法。方法:采用Zorbax ODS(250mm×4.6mm,5μm)色谱柱,以甲醇:水:磷酸(47∶53∶0.2)为流动相,流速1.0 ml.min^-1,检测波长为280nm,用甲醇提取复方金银花颗粒中黄芩苷。结果:黄芩苷在12.65-63.25ng(r=0.9996)范围内线性关系良好,平均回收率为97.02%,RSD为1.37%。结论:本方法操作简便、精密度好,适用于复方金银花颗粒的质量控制。
OBJECTIVE To establish the HPLC method for determination of scutellarin in Fufang Jinyinhua Keli.METHODS:HPLC was performed on column of Zorbax ODS(250mm×4.6mm,5μm) with methanol-water-phosphoric acid(47∶53∶0.2) as mobile phase.Flow rate was 1.0 ml·min-1 and detecting wavelength was 280nm.Scutellarin in Fufang Jinyinhua Keli was extracted by methanol reflux method.RESULTS:The calibration curve for scutellarin was linear in the range of 12.65~63.25ng(r=0.9996).The average recovery was 97.02% with RSD=1.37%.CONCLUSION:This method is simple,accurate,repeatable and effective for quality control of Fufang Jinyinhua Keli.
