Physicochemical properties and fatty acids compositions of several woody plant seeds oil

Abstract

Oil yield and physicochemical properties of Platycladus orientalis seeds oil,Pinus Tsbulaeformis seeds oil,walnut seeds oil and Toxicodendron Vernicifluum seeds oil were determined,,and then the fatty acid compositions was analyzed by GC. The total content of the unsaturated fatty acid from all kinds of seeds oil was up to over 80%.The linolenic acid of Platycladus orientalis seeds oil was especially rich,whose content was up to 45.53%,and this kind of oil had high economic value.
