    Abstract:
    This article reports the fatty acid composition of the oil extracts from Quercus brantii fruits growing in Kohgiloye va Boyer Ahmad province in southwestern Iran. The oil from Q. brantii fruits was extracted with hexane in Soxhlet apparatus and subsequently identified and determined by using gas chromatography-mass spectroscopy. The results revealed that the major fatty acids were oleic acid (52.99-66.14%), linoleic acid (10.80-11.11%), palmitic acid (8.08-10.06%), stearic acid (0.74-1.57%), α-linolenic acid (0.19-0.35%), erucic acid (0.12-0.15%) and arachidic acid (0.12-0.13%). The total proportion of unsaturated and saturated oil was 64.60-77.27% and 9.17-11.75%, respectively. Results indicate that the fruits of Q. brantii contained 0.19-0.35% omega-3, 10.92-14.77% omega-6 and 53.14-66.26% omega-9. Therefore, Q. brantii can be introduced as rich sources of fatty acid in food dietary and medical health.
