Analysis of Physicochemical Property and Composition of Fatty Acid of Almond Oil
杏仁油的物化性能及其脂肪酸组成的分析

Almond oil was extracted from almond and saponified with saturated KOH-methanol. The mixed fatty acids methylated by methanol-H2SO4(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 (C18:1), 25% linoleic acid(C18:2), 4.6%-4.8% palmitic acid(C16:0) and a little of palmitoleic acid(C16:1), stearic acid(C18:0). A trace of arachidic acid(C20:0) was also found.
