摘要:

采用索氏提取法提取籽瓜籽中的脂肪酸,用气相色谱- 质谱联用仪(GC-MS)进行分析,分离鉴定出10 种脂肪酸,其主要化学成分为亚油酸、棕榈酸和硬脂酸。用同时蒸馏- 萃取法提取籽瓜皮中的挥发性物质,用气相色谱- 质谱法从籽瓜皮的挥发油中分离并鉴定出30 种化学成分。

关键词: 籽瓜, 脂肪酸, 挥发性物质, 气相色谱-质谱(GC-MS)

Abstract:

Fatty acids were extracted from seed melon seed by Soxhlet extraction and 10 fatty acids were isolated and identified by gas chromatography-mass spectrometry (GC-MS). Linoleic acid, hexadecanoic acid and octadecanoic acid were the major fatty acids, accounting for more than 89.01% of total fatty acids. Volatile oil obtained by simultaneous distillation extraction method from seed melon seed was analyzed by GC and GC-MS. A total of 30 compounds were identified and alkane (22.44%), alcohol (17.22%), organic acids (12.86%) and ketone 2.36%) were the major components representing more than 60.55% of the oil.

Key words: seed melon, fatty acid, volatile oil, gas chromatography-mass spectrometry (GC-MS)
