Abstract :The ethanol and methanol extracts of Jojoba insert ignore into journalissuearticles values(Simmondsia chinensis insert ignore into journalissuearticles values(Link);. Schnider); leaves and seeds were screened for antioxidant activity. The antioxidative potential of ethanol and methanol extracts of Jojoba insert ignore into journalissuearticles values(Simmondsia chinensis); were investigated for the first time using DPPH 2,2-diphenyl-1-picrylhdrazyl, total phenolic contents, antioxidant activity. Total phenolic substance amounts were calculated according to Folin-Ciocalteu method, substance concentrations in mg/GAE g, equivalent to gallic acid based on mg/ml gallic acid equivalent insert ignore into journalissuearticles values(GAE);. The phenolic substance amounts in the leaves extracts insert ignore into journalissuearticles values(jojoba leaves: 313 mg/g GAE);. Free radical clearance activities of the extracts were determined by using DPPH free radical. The Phenolic substances were calculated in highest jojoba leaves and lowest jojoba seeds. When DPPH radical clearance activity results were analyzed, it was seen that the highest activity was exhibited by jojoba leaf extract insert ignore into journalissuearticles values(% 43.20, 0.5 mg/ml concentration);. The antioxidant activities of extracts were calculated in insert ignore into journalissuearticles values(nmol/g); via ascorbic acid system. When the activity scores are analyzed, higher scores were found in the ethanol extracts of jojoba leaves. The antioxidant activity was lower in the extracts with methanol.
