| 摘 要： | 介绍了一种用气相色谱法准确快速测定品中ＶＥ２含量的新方法。该法以ＶＣ作保护剂，用环已烷提取样品，ＳＥＰ－ＰＡＫ ＡＬＵＭ－Ａ小柱净化。以氯氰菊酯内标物，在１？５％ＯＶ＝－１７色谱柱上进行分离，测定化妆口中ＶＥ含量。内标物与样品的分离度为１．５５。平均回收纺为９４．３％～９８．８％，相对标准偏差为１．７％～３．５％（ｎ＝５）。

| Abstract: | A new method to determine the content of vitamin E in cosmetics by GC was studied. Vitamin E was extracted from cosmetics by homogenization with cyclohexane and vitamin C was used as the protecting agent. The cyclohexane extract was concentrated and cleaned up by passing through an alumina A cartridge. The GC used 1 5% OV 17 packed column and cypermethrin as internal standard. The resolution of vitamin E and cypermethrin is 1 55. The recoveries range from 94 3% to 98 8% with relative standard deviations from 1 7% to 3 5%( n =5). |
