中文摘要:
      比较了马鲁拉油和6种常见植物油(橄榄油、花生油、玉米油、葵花籽油、紫苏籽油、亚麻籽油)的脂肪酸组成、理化性质及角鲨烯、维生素E和β-谷甾醇等营养物质含量的差异。结果表明：马鲁拉种仁出油率高达51.93%；马鲁拉油中角鲨烯和β-谷甾醇含量分别为2.5 mg/100 g和183.5 mg/100 g；马鲁拉油中的油酸含量高达76.94%，橄榄油中油酸含量为67.39%；与常见植物油相比，马鲁拉油富含单不饱和脂肪酸，脂肪酸比例均衡，且富含营养物质，适于人体的吸收，具有开发应用的潜力。
英文摘要:
      The physicochemical properties, fatty acid compositions and nutrient contents (squalene,vitamin E and 尾-sitosterol) of marula oil and six kinds of vegetable oils were compared, including olive oil, peanut oil, corn oil, sunflower seed oil, perilla seed oil and flaxseed oil. The results showed that the oil yield of marula kernel was 51.93%.The contents of squalene and 尾-sitosterol in marula oil were 2.5 mg/100 g and 183.5 mg/100 g, respectively. The content of oleic acid in marula oil reached 76.94%, and for olive oil, it was 67.39%. Compared with common vegetable oils, marula oil was rich in unsaturated fatty acids and nutrient, and the ratio of different fatty acids was balance, thus it was suitable for human body absorption. Therefore, marula oil had a great potential for development and application.聽
