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

Abstract

Abstract: 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%.

Key words: seed kernel of Pinus armandi, fatty acid composition, physical and chemical character
