  本研究目的在鑑定化妝品常用之二十種精油對於螫合金屬離子之抗氧化能力評估,並分析其中主要螫合金屬離之子主要成分之化學成分鑑定。結果顯示試驗樣品中以羅勒精油之螫合能力最為顯著,當樣品濃品1mg/mL時,能螫合57.48%之金屬離子,半數有效抑制濃度(EC50)為984μg/Ml,以氣相層析質譜儀鑑定其主要化學成分,發現羅勒精油中主要含有甲基醚蔞葉酚、沈香醇與薄荷醇三種成分,其中以甲基醚蔞葉酚之含量最高,佔86.48%。將羅勒精油內之主要成分甲基醚蔞葉酚、沈香醇與薄荷進行螫合率之分析,發現甲基醚蔞葉酚之金屬螫合能力最佳,證明甲基醚蔞葉酚為羅勒精油中螫合金屬離子之主要成份。
20 kinds of commercial used essential oils were employed to investigate the metal chelating activity. The metal chelating activity of Basil is the best in these essential oils. 1mg/mL of Basil essential oil was shown 57.48% of the metal chelating activity and its EC50 is 984μg/mL. 86.48% of methyl chavicol in Basil essential oil was analyzed by GC-MS. Three major compositions of Basil essential oil are methyl chavicol, linalool and menthol and those were used to test metal chelating ability. Methyl chavicol was shown the best metal chelating ability of the three chemical compositions and it is the major metal chelating activity compound of Basil essential oil.
