三种常用香料的微量分析方法研究

【摘要】 本文建立了桂醛、羟基香茅醛、异丁香酚三种常用香料的气相色谱分析方法，桂醛、羟基香茅醛经离体皮肤渗透后，其渗透液直接作为测定液，异丁香酚的渗透液经乙醚萃取处理后进样，用SE－30固定液，FID检测器，本法线性范围桂醛、羟基香茅醛、异丁香酚分别为0－100mg／ml、0－30mg／－ml、0－20mg／ml，最低检测限分别为5.3x10-9g2．1x10-9g2．9x10-9g，变异系数分别为0．7－3．2％、0．7－2．9％、1．2－2．7％，回收率分别为96．3％、87．4％、90％。更多还原

【Abstract】 A method has been developed for tho analysis of three kinds of comrnon perfumes (cinnamic aldehyde, hydroxycitronellal and isoeugenol) inosmotic liquid of percutaneous penetration in vitro. The amounts of these compounds are quantitated by GC on SE-30 column with FID dectetor, the linnear rangs of cinnamic aldehyde, hydroxycitronellal and isoeugenol are 0-100mg/ml, 0-30mg/ml, 0-20mg/ml respectively, the limits of dectetion are 5.3 X 10-9g, 2.1 x 10-9 g, 2.9x 10-9g respectively, C.V. rangs from 0.7 to 3.2 %, 0.7 to 2.9 %, 1 .2 to 2.7% respectively, the average recoveries of these are 96.3 %, 87.4%, 90% respectively.更多还原
