Antioxidant and inhibition of xanthine oxidase potentials of fluidized bed extracts fromleaves of the ash tree

Emanuel Vamanu, Andreea Mihaela Ilie

The aim of the study was to determine both the antioxidant and inhibition potentials of the activity of xanthine oxidase by ethanol and methanol extracts in a fluidized bed of leaves of the ash tree. In traditional medicine, this plant is well known for its anti-inflammatory properties, especially against gout. The best results were obtained with methanol extract in the case of evaluation of antioxidant potential, and with ethanolic extract in reference to the inhibition activity of xanthine oxidase. The values calculated for different methods of valuation in vitro were correlated with the phytocontent of the two lyophilized extracts.
