Fatty acid compositions of Pinus koraiensis seed

Abstract

The fatty acid compositions of two years samples of Pinus koraiensis seed were analyzed by gas and gas-liquid chromatography. The fatty acid compositions between the two years samples were almost identical. The seed oil consisted of 21 fatty acids whose chain lengths are from 14:0 to 22:0. The seed oil contained three nonmethylene-interrupted polyenoic (NMIP) acids - 18:3Δ5, 9, 12, 20:2Δ5, 11, and 20:3Δ5, 11, 14 - as omega - 5 fatty acids. The total amounts of three omega-5 fatty acids was 12.38%; and among these 18:3Δ5, 9, 12 acid was greatest, 11.14%. The seed contained oleic acid (28.40%) and linoleic acid (47.92) as major fatty acids. The ratio of poly unsaturated to saturated fatty acids was 7.04. The fatty acids compositions of Pinus koraiensis seed are ideal for hypolipemic effects. Since the koraiensis seeds has been claimed for curing and/or preventing degenerative chronic diseases, i.e. heart disease and diabetes, the effects of omega-5 fatty acids on lipids and glucose metabolism can be studied with Pinus koraiensis seeds. © 1989 Pergamon Press plc.
