The purpose of this study is to evaluate total phenol and flavonoids and antioxidant effects of beech and hornbeam and spruce; bark. Beech and hornbeam species of northern hardwood and spruce; species of planting trees, despite of their abundance, very little information about the chemical composition of their skin and their application is presented. Antioxidant compounds that prevent disease outbreaks and destruction of food can also be extracted from the skin these plants. After preparation of the bark, acetone extracts were obtained by soxhlet. First, the amount of total phenol and flavonoid extracts measured and then for evaluating the antioxidant properties of extracts; regenerative power and hydrazyl diphenyl pykryl methods were used. The results showed that the amount of phenol and flavonoids were highest in the bark of hornbeam and lowest in the bark of beech. Test results or trapping free radicals DPPH1 shpwed inhibitory concentrations 50% acetone extract of the bark of beech, hornbeam and spruce; respectively, 07.63, 17.33 and 3.86 micrograms per milliliter, respectively. Also beech extracts has more regeneration power compare with other species.
