Özet: Propolis is a resinous natural product collected by bees (Apis mellifera) from tree exudates which is widely used in folk medicine1. Reports on Jordanian Propolis reveal the presence of new chemical compound 4(Z)-1-3-dihydroxyeupha-7,24-dien-26-oic acid2 along with other compounds like pinobanksin-3-O-acetate, pinocemberin, chrysin3 and lignoceric acid2. The present study was carried out to investigate the fatty acid composition, antioxidant and xanthine oxidase inhibition activity of Jordanian Propolis, collected from Al-Ghour region. The hexane extract of Jordanian Propolis contains different fatty acids, which are reported first time, using GC-FID. The major fatty acid identified were palmitic acid (44.5%), Oleic acid (18:1 ∆9cis, 24.6%) , Arachidic acid (7.4%), Stearic acid (5.4%), linoleic acid (18:2 ∆9-12cis, 3.1% ), caprylic acid (2.9%),  lignoceric acid (2.6%), cis-11,14-eicosadienoic acid (20:2 ∆11-14cis, 2.4%), palmitoleic acid (1.5%), cis-11-eicosenoic acid (1.2%), α–linolenic acid (18:3 ∆9-12-15cis, 1.1%), cis-13,16-docosadienoic acid (22:2 ∆13-16cis, 1.0%), along with minor constituents like saturated fatty acids. Antioxidant properties of the hexane extract were determined via DPPH radical scavenging, β-carotene bleaching assay and NO scavenging assay. The extract produced significant antioxidant activity in-vitro. The extract also exhibit appreciable xanthine oxidase inhibitory activity in-vitro.
