摘要:

对黑芝麻和白芝麻中脂肪酸组成进行分析比较。采用索氏提取法提取黑芝麻和白芝麻中脂肪油,再以氢氧化钾- 甲醇溶液进行甲酯化处理,以气相色谱- 质谱联用仪分离和鉴定脂肪酸的组成和相对含量。结果表明,由黑芝麻中分离鉴定出21 种脂肪酸,其中不饱和脂肪酸占71.30%;白芝麻中分离鉴定出20 种脂肪酸,其中不饱和脂肪酸占73.58%。

关键词: 黑芝麻, 白芝麻, 脂肪酸, 气相色谱- 质谱联用

Abstract:

Oil in black sesame and white sesame seeds was obtained by Soxhlet extraction and esterfied with methanol solution of potassium hydroxide for analyzing fatty acid composition by gas chromatography-mass spectrometry (GC-MS). There were 21 and20 fatty acids identified in black sesame and white sesame seed oil, of which, unsaturated fatty acids accounted for 71.30% and 73.58%, respectively.

Key words: black sesame, white sesame, fatty acid, GC-MS
