摘　　要：采用脲素包合法对华山松籽油中的不饱和脂肪酸进行了分离,并对其主要成分及降血脂作用进行了研究。结果表明,华山松籽油中的不饱和脂肪酸组成为亚油酸915.3g/kg,油酸60.7g/kg,亚麻酸4.0g/kg。华山松籽油不饱和脂肪酸中剂量组和高剂量组小鼠血清中甘油三酯(TG)水平显著或极显著低于高脂模型组(中剂量组P<0.05,高剂量组P<0.01);低剂量组、中剂量组、高剂量组小鼠血清中总胆固醇(TC)和低密度脂蛋白(LDL-C)水平及动脉硬化指数(AI)显著或极显著低于高脂模型组(低剂量组P<0.05,中、高剂量组P<0.01);中剂量组、高剂量组小鼠血清中高密度脂蛋白(HDL-C)水平显著或极显著高于高脂模型组(中剂量组P<0.05,高剂量组P<0.01),说明华山松籽油不饱和脂肪酸对小鼠的高血脂症和动脉硬化有显著抑制作用。Unsaturated acids were separated and purified from the seed kernel oil of Pinus armandi via urea clathration. The composition of fatty acids was analysed via GC. The oil consisted mainly of linoleic acid 915.3 g/kg,oleic acid 60. 7 g/kg,α-LNA 4.0 g/kg. The results showed that the level of the serum TG was far lower than that of high fat chow control group （middle dose group P〈0. 05,high dose group P〈0. 01） and that the level of the serum TC and LDL-C and AI were even lower than that of high fat chow control group （low dose group P〈0.05,high and middle dose group P〈0.01） and that the level of the serum HDL-C was much higher than that of high fat chow control group （middle dose group P〈0.05,high dose group P〈0.01）. It is concluded that the unsaturated acids in seed kernel oil of Pinus armandi could prevent rats＇ hyperlipemia and arterioseclerosis.
