华山松籽油脂肪酸组成及其理化性质研究

Study of Fatty Acid Composition and Physical and Chemical Character of Seed Kernel Oil of Pinus armandi

通过气相色谱(GC)分析了华山松籽油的主要脂肪酸组成。结果表明华山松籽含油率为56.5%,其中主要含有亚油酸63%,油酸26%,棕榈酸5%,硬脂酸2%,花生酸1%,芥酸1%,不饱和脂肪酸总量达90%。理化测定结果表明华山松籽油相对密度为0.915,折光率为1.4778,酸价为5.1,皂化价为190.8,碘价为142.6,过氧化值为0.04305%。

The composition of fatty acids in the seed kernel oil of Pinus armandi was studied by Gas chromatography (GC).The results showed that the oil contents of seed kernel of Pinus armandi was 56.5%. The oil mainly consisted of linoleic acid 63%,oleic acid 26%, palmitic acid 5%, stearit acid 2%, arehidic acid 1%, erucic acid 1%. The total amount of the unsaturated fatty acidwas 90%. Physical and chemical tests results showed that spcific gravity is 0.915, refactive index is 1.4778, acid value is 5.1,saponitication value is 190.8, iodine value is 142.6 and POV is 0.04305%.
