Abstract :The present study was designed to examine the chemical composition and the antioxidant activity of Bunium incrassatum extracts prepared in five different solvents with increasing polarities. RP-HPLC analysis resulted in the identification of 12 phenolic compounds, including 8 phenolic acids insert ignore into journalissuearticles values(caffeic acid, ellagic acid, ferulic acid, gallic acid, rosmarinic acid, sinapic acid, syringic acid, and vanillic acid); and 4 flavonoids insert ignore into journalissuearticles values(catechin, hesperetin, luteolin, and quercetin);. Two different test systems were used to assess the antioxidant activity: DPPH and β-carotene/linoleic acid assays. Methanol extract exhibited the highest DPPH scavenging potential and even low inhibitory effect against β-carotene bleaching, whereas chloroform extract showed the highest effect against β-carotene bleaching and a weak scavenging potential. As expected, methanol extract recorded the highest content of total phenolics insert ignore into journalissuearticles values(26.57±0.15 mg GAE/g E);, while chloroform extract has been found to be the richest in flavonoids.
