| description | Abstract
Background & aim: Anti-oxidant compounds prevent prevalence of chronic diseases and food spoiling. The aim of this study was to evaluate the total phenolic and flavonoid content and antioxidant activity of beech and oak barks.
Methods: In this experimental study, the skin of beech and oak trees were prepared and then acetone extraction was obtained using Soxhle method. At the beginning, total phenol and flavonoid of extracts were determined and the anti-oxidant properties of the extracts were then evaluated by three methods (methods Biphenyl Pykryl Hydrosol, regenerative power produced- and nitric oxide).
Results: The amount of phenolic was higher in bark of beech trees, but flavonoids were higher in oaks. The result of test to trap free radicals of Biphenyl Pykryl Hydrazyl showed the inhibitory concentration 50% of acetone extract of the bark of beech and oak, were 92.19 and 33.7 mg/L respectively. Beech extracts had greater regenerative power than oak. In Nitric oxide trap test acetone extract inhibited 50% in bark of beech trees was 98/23 and the oak extract was 92/90 mg/L respectively.
Conclusion: Acetone extract of the bark in three models showed varying degrees of anti - oxidant activity. Beech extract had better antioxidant activity compared with oak extract.
