以车厘子核为原料，采用索氏抽提法提取车厘子核油，并对其理化性质、脂肪酸组成、脂溶性营养成分、抗氧化活性及挥发性成分进行分析。结果表明：车厘子核油得率为（10.13±0.19）%，其酸值、过氧化值均符合GB 2716—2018要求；车厘子核油中有8种脂肪酸，主要是油酸（58.69%）和亚油酸（26.03%）；车厘子核油富含甾醇，含量高达530.04 mg/100 g，以β-谷甾醇（428.00 mg/100 g）为主；车厘子核油抗氧化能力强，对DPPH自由基和羟自由基均有较好的清除效果，其IC50值分别为12.51 mg/mL和1.92 mg/mL；车厘子核油中检出58种挥发性成分，以醛类物质（44.27%）和烃类物质（28.44%）为主，有特殊的果香味。 The cherry kernel oil was extracted by Soxhlet method with cherry kernel as raw material, and its physicochemical properties, fatty acid composition, fat-soluble nutritional component, antioxidant activity and volatile components were analyzed. The results showed that the yield of cherry kernel oil was (10.13±019)%, and the acid value and peroxide value of cherry kernel oil met the requirement of GB 2716-2018. There were eight kinds of fatty acids in the cherry kernel oil, mainly oleic acid (58.69%) and linoleic acid (26.03%).Cherry seed oil was rich in sterols, which reached 530.04 mg/100 g, and β-sitosterol was dominant (428.00 mg/100 g). Cherry kernel oil had strong antioxidant ability and had good scavenging effects on DPPH free radical and hydroxyl free radical, and their IC50 values were 12.51 mg/mL and 1.92 mg/mL, respectively. There were 58 volatile components detected in the cherry kernel oil, and aldehydes(44.27%) and hydrocarbons(28.44%) were the main compounds.The cherry kernel oil had special fruit flavor.
