摘 要:目的:建立HPLC法同时测定益气养血口服液中苯甲酸、山梨酸钾、羟苯甲酯、羟苯乙酯、羟苯丙酯、羟苯丁酯6种防腐剂的含量。方法:采用Agilent 5TC-C_(18)(250 mm×4.6 mm,5μm)色谱柱:以甲醇-0.01 mol/L乙酸铵溶液为流动相,梯度洗脱,流速为1.0 mL/min;检测波长为230 nm(0~11 min,苯甲酸);256 nm(11~40 min,山梨酸钾、羟苯酯类);进样量为10μL,柱温为25℃。结果:6种防腐剂在各自线性范围内线性关系良好(r≥0.9998);平均加样回收率分别为99.9%~104.3%,RSD分别为0.53%~1.40%(n=6)。结论:本法简便、灵敏,重现性好,可用于益气养血口服液的防腐剂的限量测定。Objective To establish an HPLC method for the simultaneous content determination of benzoic acid,potassium sorbate,methyl p-hydroxybenzoate,ethyl p-hydroxybenzoate,propyl p-hydroxybenzoate,butyl p-hydroxybenzoate in Yiqi Yangxue Oral Liquid.Methods The chromatographic separation was performed on an Agilent 5TC-C_(18)column(250 mm×4.6 mm,5μm)column with Methanol-0.01mol/L ammonium acetate acid solution as the mobile phase(gradient elution).The flow rate was 1 mL·min^(-1)and the detection wavelengths were set at 230 nm for benzoic acid,256 nm for potassium sorbate,methyl p-hydroxybenzoate,ethyl p-hydroxybenzoate,propyl p-hydroxybenzoate,butyl p-hydroxybenzoate.the injection volume wad 110μL,the Column temperature was set at 25℃.Results Six preservatives showed good linear relationship within their own ranges(r≥0.9995),whose average recoveries were 99.9%-104.3%with the RSDs of 0.53%-1.40%(n=6).Conclusion The method was stable,sensitive and reproducible,which can be used for the determination of preservatives of Yiqi Yangxue Oral Liquid.
