| Abstract: | The almond oil extracted out and enhanced in hexane by ultrasonic wave was esterified by KOH-CH_3OH solution and was analyzed by GC-MS. The analysis results indicate that the main compositions of the fatty acids in Shaanxi Pucheng almonds are oleic acid, 8,11-Octadecadienoic acid, 9-Hexadecenoic acid, Octadecanoic acid and Hexadecanoic acid. The content of unsaturated acids is more than 91.4%, and the content of the oleic acid is more then 73.3% among them. |
