高效液相色谱法测定化妆品中香豆素类化合物
Journal of Analytical Science(2011)
Abstract
应用高效液相色谱法测定化妆品中二氢香豆素、双香豆素、7-甲氧基香豆素和醋硝香豆素、7-甲基香豆素和7-乙氧基-4-甲基香豆素6种香豆素类化合物.用无水乙醇为提取剂进行超声快速提取,优化了液相色谱分离条件,外标法定量,6种香豆素的平均回收率(n=10)在83.2%~109.5%范围,相对标准偏差在6.2%~11.0%之间,二氢香豆素、醋硝香豆素、7-乙氧基-4-甲基香豆素的检出限为0.3 mg/kg,双香豆素、7-甲氧基香豆素的检出限为0.2 mg/kg,7-甲基香豆素的检出限为0.5 mg/kg.该方法简单、快速、准确、无污染.
