【摘要】 采用索氏提取法对水黄瓜中脂肪酸进行了提取,以气相色谱-质谱联用仪进行了分析,分离鉴定出11种脂肪酸,并对其主要成分进行了鉴定,主要化学成分为:9,12-十八碳二烯酸和9,12,15-十八碳三烯酸.用同时蒸馏-萃取法提取水黄瓜中挥发性物质,测得水黄瓜挥发油的含量为1.0%,用GC/MS法从水黄瓜挥发油中分离并确定出24种化学成分.用峰面积归一化法通过化学工作站数据处理系统,得出各化学成分在挥发油中的相对百分含量.更多还原

【Abstract】 The fatty acids of cucumber are extracted by Soxhlet extraction,11 fatty acids are separated and identified by GC-MS.The major fatty acids are 9,12-Octadecadienoic acid and 9,12,15-Octadecatrienoic acid.The simultaneous distillation extraction method is used for extracting the volatile substances of the cucumber,the average oil yield obtained is 1.0%.24 chemical components were identified by GC / MS method.更多还原
