Effect of extraction solvent on antioxidant properties of extractof Solanum melongena

In this research, antioxidant activity of the peel of fruits from Solanum melongena L., cultivated in Iran,was evaluated for the first time. The results, exhibited significant antioxidant activity in the studiedsample. To evaluate quantitative and qualitative effects of microwave irradiations on the extractedsample, yields and antioxidant activities of the extracts, prepared by soxhlet and microwave assistedmethod were compared. Antioxidant activity was evaluated via DPPH method with BHT as standard.The results showed that both extracts have high potential to scavenge free-radical compared with BHTstandard antioxidant; these active antioxidants are extracted under microwave irradiations with highyield; these irradiations have no destructive effect on antioxidant compounds of the plant, during a shorttime, and also yields of extractions of the mentioned methods are not highly different. these active antioxidants are extracted under microwave irradiations with highyield; these irradiations have no destructive effect on antioxidant compounds of the plant, during a shorttime, and also yields of extractions of the mentioned methods are not highly different.
