水果黄瓜和旱黄瓜脂肪酸的分析

Analysis of Fatty Acids for Fruit Cucumber and Dry Cucumber

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%)。

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.
