| 中文摘要:本文建立了心脑脉舒口服液中阿魏酸含量测定方法。色谱柱:YWG-C18,4.0×150mm;流动相:甲醇-水-冰乙酸(33:66:1);流速:1.0m1/min;UV检测波长:320mm.结果表明,方法快速、准确、灵敏、重现性好。阿魏酸浓度在0.2～1.0μg/μ1范围内线性关系良好(γ=0.9998),加样回收率为96.74%,RSD=2.7%,实际测定10批样品结果满意。 |

| Abstract:The high performance liquid chromatography (HPLC) method was established for determination of ferulic acid in xinnao Maishu Oral Liquid.Chromatographic conditions were:column,YWG-C18(4.0±150mm);mobile phase, methanol-water-acetic acid(33:66:1);flow rate,1.0ml/min;the UV wavelength used for detector was 320nm.The results proved that this method was rapid,accurate,sensitive,and reproducible. The good linear correlation was observed from the concentrations of 0.2μg/μl.0μg/μl(γ=0.9998),and the average recovery was 96.74%,with a relative standard deviation of 2.7%,The results of determination for 10 samples were satisfactory. |
