摘要
建立高效液相色谱法测定麻杏止咳糖浆中苦杏仁苷含量的方法。采用KromasilC18柱,乙腈-0.1%磷酸溶液(8∶92)为流动相,流速1.0mL·min-1,检测波长207nm。苦杏仁苷在0.0406~0.812μg范围内有良好的线性关系, r=0.9999,平均回收率为99.0%,RSD为0.25%。本方法简便、准确、重现性好,可用于麻杏止咳糖浆的质量控制。
A HPLC method for determination of amygdalin in Maxing cougy syrup by HPLC was established.Applied KromasilC18 column(250mm×4.6mm,5μm), the mobile phase was acetonitrile-0.1% phosphoric acid solution(8:92), the flow rate of 1.0mL·min-1, the detecting wavelength was at 207nm. The linear range of amygdalin was 0.0406~0.8112μg (r=0.9999),the average recovery was 99.0%, RSD was 0.25%.The method was simple,accurate and reproducible,it could be used for quality control of maxing cough syrup.
