摘　　要：采用超临界CO_2工艺萃取得到细齿樱桃籽油及其挥发油并对其抗氧化活性和化学成分进行分析。结果表明:细齿樱桃籽油具有较高的抗氧化活性,其成分由14种脂肪酸组成,其中不饱和脂肪酸占88.12%,主要为油酸(47.09%)和亚油酸(38.69%)。细齿樱桃籽挥发油经气相色谱-质谱联用-自动质谱退卷积定性系统(gas chromatography-mass spectrometry-automocted mass spectral deconfolotion and iderclification system,GC/MS/AMDIS)分析,鉴定出17种主要物质,其中主要成分是具有多种药理学活性的β-谷甾醇(60.3%)。Seed oil and volatile oil from serration cherry have been extracted by supercritical CO_2,their antioxidant activities and chemical composition were analyzed. The results show that seed oil had a high antioxidant activity,composed of 14 fatty acids,88. 48% of which was the unsaturated fatty acid. The main components of seed oil were oleic acid（ 47. 09%） and linoleic acid（ 38. 69%）. The GC/MS/AMDIS analysis demonstrated that 17 kinds of major substance in volatile oil,60. 3 % of which was β-sitosterol,whith has a variety of pharmacological activities.
