【摘要】 用 ３ 种不同溶剂萃取杏仁得到杏仁油，并对其物化常数进行测定。杏仁油用饱和氢氧化钾甲醇皂化，再用甲醇硫酸（体积比为 ４∶１）甲酯化后，将乙醚萃取液作气相色谱分析。太原杏仁油中脂肪酸的主要成分为油酸（ Ｃ１８∶１，质量分数约 ６８％ ）和亚油酸（ Ｃ１８∶２，质量分数约 ２５％ ），少量棕榈酸（ Ｃ１６∶０）、棕榈烯酸（ Ｃ１６∶１）和硬脂酸（ Ｃ１８∶０），微量花生酸（ Ｃ２０∶０）。更多还原

【Abstract】 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.更多还原
