摘要: 对黑花生和白花生中脂肪酸进行分析比较。采用索氏提取法提取黑花生和白花生中脂肪油,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:从黑花生中分离鉴定出19 种脂肪酸,不饱和脂肪酸占61.07%;从白花生中分离鉴定出17 种脂肪酸,不饱和脂肪酸占67.59%。

关键词: 黑花生, 白花生, 脂肪酸, 气相色谱-质谱联用

Abstract: The fatty acid profiles of black and white peanuts were analyzed and compared. The lipid fractions in black and white peanuts were extracted by Soxhlet extraction, followed by esterification with a potassium hydroxide/methanol solution. The fatty acid methyl esters (FAME) were analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 19 and 17 fatty acids were identified in black and white peanuts, respectively. Unsaturated fatty acids represented 61.07% and 67.59% of the total fatty acids in black and white peanuts, respectively.

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