Effect of solvent type on bioactive compounds and antioxidant activity of White mahlab L. juice

The purpose of current research, was evaluated the effect of three types of extraction solvent including water, ethanol and methanol on extraction yield, total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity using DPPH and H2O2 methods of White mahlab L extract. Results revealed that ethanolic extract had the highest extraction yield (3.33%) while methanolic extract showed the highest TPC (3.79±0.09 mg GAE/ g sample) and TFC (0.16±0.0007 mg Rutin/g sample) in comparison with other studied extracts. Furthermore, methanolic extract had the highest DPPH and H2O2 antioxidant activity at concentration of 0.005 (64.29±1.81 and 2.28±0.05%, respectively). According to the results obtained from this study, it is possible to introduce methanolic extract of White mahlab L. fruits which in our country there is no significant, as potential natural source of useful bioactive compounds with high antioxidant activity for application in food and drug industry.
