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.
从杏仁中提取杏仁油，并用饱和氢氧化钾 - 甲醇溶液进行皂化。混合脂肪酸用甲醇 - 硫酸（4:1，V/V）进行甲基化。甲酯用乙醚萃取，并用气相色谱法进行检测。结果发现，太原杏仁油中的主要脂肪酸约为68%的油酸（C18:1）、25%的亚油酸（C18:2）、4.6% - 4.8%的棕榈酸（C16:0）以及少量的棕榈油酸（C16:1）、硬脂酸（C18:0）。还发现了微量的花生酸（C20:0）。
