The regularity of fatty acid component and contents changes in the seed kernel oil of Xanthoceras sorbifolia in different areas.

The paper aimed that distilling and analyzing the seed kernel oil of Xanthoceras sorbifoLia Bunge.The method of the oil analysis was gas chromatography(GC).The results are as follows the oil contained 11 kinds of fatty acid,such as palmitic acid(C16∶0),stearic acid(C18∶0),oleic acid(C18∶1),linoleic acid(C18∶2),arachidic acid(C20∶0),linolenic acid(C18∶3),11c,14c-eicosadienoic acid(C20∶2),docosanoic acid(C22∶0),mead acid(C20∶3),tetracosanoic acid(C24∶0),nervonic acid(C24∶1) and so on.The carbon numbers of the fatty acids were mainly from 16 to 18,which was suited to produce biodiesel.The authors included that: the trend of the fatty acids contents,such as C18∶2,C20∶3,C18∶3,C20∶2,C22∶0,C24∶0,C24∶1,were improved with the latitude and longitude increase,but C18∶1 content was decreased.And other fatty acids contents such as C16∶0,C20∶0,C18∶0 increased with the latitude increase or the longitude decrease.
