The paper aimed that distilling and analyzing the seed kernel oil of Xanthoceras sorbifoL ia Bunge. Themethod of the oil analysis was gas chromatography (GC). The results are as follows the oil contained 11 kinds offatty 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 p roduce biodiesel. The authors included that: the trend ofthe fatty acids contents, such as C18∶2, C20∶3, C18∶3, C20∶2, C22∶0, C24∶0, C24∶1, were imp roved 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.
