摘要: 采用索氏提取法对水果黄瓜和旱黄瓜中脂肪酸进行了提取,以气相色谱-质谱联用仪分别进行了分析。分离鉴定出11种脂肪酸,并对其主要成分进行了鉴定,水果黄瓜中主要化学成分为:9,12-十八碳二烯酸(15.88%)和9,12,15-十八碳三烯酸(35.77%)。旱黄瓜中主要化学成分为:9,12-十八碳二烯酸(15.41%)和9,12,15-十八碳三烯酸(24.24%)。

Abstract: The fatty acids of fruit cucumber and dry cucumber were extracted by Soxhlet extraction, 11 fatty acids were separated and identified by GC-MS. The major fatty acids are 9,12-octadecadienoic acid (15.88%) and 9,12,15-octadecatrienoic acid (35.77%) for fruit cucumber and 9,12-octadecadienoic acid (15.41%) and 9,12,15-octadecatrienoic acid (24.24%) for dry cucumber.

Key words: fruit cucumber, dry cucumber, fatty acid, separation and identification, GC-MS
