Analysis of Physicochemical Property and Composition of Fatty Acid of Almond Oil

Shi Ziwen, Fu Qizhong, Chen Bangjie, Xu Shuying (Shanxi Institute of Coal Chemistry, The Chinese Academy of Sciences, Taiyuan 030001, China)  
Almond oil was extracted from almond and saponified with saturated KOH methanol. The mixed fatty acids methylated by methanol H 2SO 4(4∶1,V/V).Methyl esters were extracted by ether and detected by gas chromatography. The major fatty acids in Taiyuan almond oil were found to be about 68% oleic acid(C 18∶1 ), 25% linoleic acid(C 18∶2 ), 4.6% 4.8% palmitic acid(C 16∶0 ) and a little of palmitoleic acid(C 16∶1 ),stearic acid(C 18∶0 ).A trace of arachidic acid(C 20∶0 )was also found.
