Abstract
The ethanol and methanol extracts of Jojoba (Simmondsia chinensis (Link). Schnider) leaves and seeds were screened for antioxidant activity. The antioxidative potential of ethanol and methanol extracts of Jojoba (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 FolinCiocalteu method, substance concentrations in mg/GAE g, equivalent to gallic acid based on mg/ml gallic acid equivalent (GAE). The phenolic substance amounts in the leaves extracts (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 (% 43.20, 0.5 mg/ml concentration). The antioxidant activities of extracts were calculated in (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.
