摘　　要：用GC-MS分析木菊科植物茵陈挥发油的化学组成并研究其抗氧化活性。采用水蒸气蒸馏法提取挥发油,用GC-MS进行成分分析,用分光光度法测定茵陈挥发油对DPPH·和·OH的清除率。结果表明,20个化合物结构被确定,占挥发油总量的96.6%,主要成分为棕榈酸(33.1%)、氧化石竹烯(19.1%)和匙叶桉油烯醇(9.9%)。茵陈挥发油对DPPH.和.OH具有良好的清除作用,抗氧化活性较强。茵陈挥发油的主要成分为棕榈酸(33.1%)和氧化石竹烯(19.1%),并具有强大的抗氧化活性,在食品和医药产业具有广泛的应用前景。This paper studied the constituents of essential oil from Artemisia capillaries Thunb by GC - MS and examined the antioxidant effects of it. Essential oil was extracted by steam distillation （SD）. The chemical constituents of essential oil was analyzed by GC - MS. Using spectropho- tometric method determined the clearance rates of DPPH＂ and＂ OH. The results showed that twenty compounds were identified representing 96.4% of the essential oil. The main components were n- hexadecanoic acid（33.1% ）, caryophyllene oxide（ 19.1% ） and spathulenol （9.9 % ）. The essential oil of Artemisia capillaries Thunb had good effects on clearing DPPH· and·OH, so it had a strong antioxidant activity. The main components of the essential oil of Artemisia capillaries Thunb were n - hexadecanoic acid （ 33.1% ） and caryophyllene oxide （ 19.1% ）. The essential oil exhibited a strong antioxidant activity, which possessed a good potential for use in the food and pharmaceutical industry
