Fatty acid composition and physiochemical properties of Decaisnea fargesii Franch seed oil

The oil was obtained from Decaisnea fargessi Franch seed by cold press method.The fatty acid composition of the oil was identified by gas chromatography(GC) and the physiochemical properties of the oil were tested.The result showed that Decaisnea fargessi Franch seed oil was light yellow and had a faint scent.The main fatty acid of the oil was palmitoleic acid and its content reached 49.9%,the other components were as follows: myristic acid 0.2%,palmitic acid 7%,stearic acid 1.7%,oleic acid 27.5%,linoleic acid 10.1%,linolenic acid 0.8%.In addition,the acid value,iodine value and peroxide value of the oil were 3.1 mg/g,97 gI/100 g and 3.9 mmol/kg,respectively.
