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.
