摘要
目的研究建立用气相色谱-质谱联用法测定化妆品中黄樟素、6-甲基香豆素的方法。方法样品用甲醇提取,超声后定容,脱水,经0.45μm滤膜过滤,用GC-MS法定性,外标法定量。结果方法的回收率为101.3%～106.0%,RSD为0.9%～1.4%(黄樟素),0.9%～2.1%(6-甲基香豆素),黄樟素和6-甲基香豆素的测定限(以S/N=10计)分别为5、10μg/g。结论该方法准确度和灵敏度均较高,样品用量少,检测周期短,用于测定化妆品中黄樟素、6-甲基香豆素的含量,结果满意。
Objective To develop a method for separation and determination of safrole and 6-methyl coumarin in cosmetics by GC-MS. Methods The cosmetics were extracted with methanol and then dehydrated,and filtrated through the membrane of 0.45μm. The filtration liquid was injected into GC and GC-MS for detection and quantitative analysis with external standard method. Results The recovery rates of safrole and 6-methyl coumarin were 101.3%-106.0% and relative standard deviations of safrole and 6-methyl coumarin were 0.9%-1.4% and 0.9%-2.1% respectively. The detection limits were 5 and 10μg/g. Conclusion This method is accurate and sensitive for detection of safrole and 6-methyl coumarin in cosmetic.
