一测多评法同时测定感冒退烧片中4种异黄酮成分
【摘要】目的:建立一测多评法(QAMS)同时测定感冒退烧片中葛根素、3’-甲氧基葛根素、大豆苷、大豆苷元的含量。方法:采用高效液相色谱法,以AgilentZorbaxSB-C18柱(250mm×4.6mm,5μm)为色谱柱,柱温30℃;流动相乙腈-0.4%磷酸,梯度洗脱,流速为1.0mL/min;检测波长为250nm。以葛根素为内标,计算其他3种异黄酮成分的相对校正因子,计算其含量。结果:4种异黄酮成分在各自范围内线性关系良好,各相对校正因子重复性良好,一测多评法所得结果与外标法接近,相对平均偏差<5.0%。结论:QAMS法方法新颖,简捷准确,节约成本,可用于感冒退烧片的质量控制。【关键词】一测多评法;感冒退烧片;葛根素;含量测定;相对校正因子
