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
