The purpose of the study was to analyze the po-tential health-pro mo ting components of some edible forest species of fruits. These are Service tree (Sor-bus domestica), Black rosehip (Rosa pimpinelli-folia), Red rosehip (Rosa carina), Bay fruit {Lawns nobilis), Cornelian cherry (Cornus mas), Autumn-olive (Elaeagrtus umbellate), and two different blue-berry fruits (Vaccinium arctostaplylos and Vaccin-ium myrtillus). In the present study, chemical and an-tioxidant activities, phenolic compounds as well as, inhibition effects on important enzymes (acetylcho-linesterase, xanthine oxidase and urease) of fruits were studied. Total polyphenol, flavonoid content, and the in-vitro antioxidant activity were evaluated by DPPH and FRAP. The sugar contents and phe-nolic compounds of the fruits were analyzed by HPLC-RJD and HPLC-UV. Fruits was determined the total polyphenol content (TPC) 1.10 to 19.87 mgGAE/g, total flavonoid content (TFC) 0.01 to 0.80 mgQE/g, DPPH values 0.22 to 6.03 mg/mL and FRAP values 4.24 to 168. 02 umol FeSO47H2O/g. All samples were determined various rate fructose and glucose. HPLC-UV revealed fruits contained different phenolic compounds. Inhibition values of the enzymes were expressed as inhibition concentra-tion (IC50: Mg/mL or ug/mL). It can be concluded that edible forest fruits are a potential source of anti-oxidants with therapeutic importance as well a natu-ral enzyme inhibitor.
