Abstract:
The aim of the study is to investigate the composition of the oil content and the fatty acids in different varieties (i.e. NC-7, Batem-5025, Osmaniye-2005, Sultan, and Halisbey) of peanut (Arachis hypogaea L.) grown in the province of Osmaniye in Turkey. Batem-5025 provided the greatest percentage of oil with 50.30%. Higher concentrations in oil specimens were found for oleic and linoleic acids. The fatty acids in the all varieties were oleic (51.32-62.43%), linoleic (18.27-27.54%), palmitic (8.35-9.69%), stearic (2.64-3.36%), behenic (2.56-2.85%), arachidic (1.43-1.62%), and lignoceric (1.15-1.53%) acids listed in order of concentration. The saturated fatty acids were observed to be far less than the unsaturated ones (80.07-81.88%) in any of the varieties. The varieties of NC-7 and Osmaniye-2005 had oleic and linoleic acids at the highest concentration and stearic and palmitic acids at the lowest, respectively. NC-7 showed the best oleic-to-linoleic (O/L) ratio with 3.41.
