    【摘要】 目的:建立蜂胶中高良姜素的含量测定方法。方法:采用HPLC法,Diamonsil(钻石)C18(46 mm×250mm,5μm)色谱柱,甲醇-0.4%的磷酸水(65∶35)为流动相,流速为1.0 ml/min,检测波长为256 nm。结果:高良姜素在0.00412~0.02472 mg/ml范围内呈良好的线性关系(r2=0.9998);高良姜素的含量,山东最高,为11.7 mg/g,其次是内蒙和河南,分别为10.5 mg/g,10.3 mg/g,甘肃最低为9.8 mg/g。结论:本方法简便、可靠,适用于峰胶中高良姜素的含量测定。 更多还原

    【Abstract】 Objective: To establish an HPLC method for determination of galangin in propolis.Methods: HPLC method was established.Diamonsil C18 column was used,CH3OH-4%H3PO4 solution(65∶35) as mobile phase,at the flow rate of 1.0 ml/min and the UV detection wavelength at 256 nm.Results: The linear of galangin was 0.00412~0.02472 mg/ml(r2=0.9998).The content of galangin was the highest in the propolis from Shandong(11.7 mg/g). The content of galangin was higher in the propolis from Neimeng and Henan,respecti... 更多还原
