In this study the characteristics of the fruits of R. pimpinellifolia as a naturally grown and wild species in Bayburt was investigated. The antioxidant property of this fruit was determined by using four different methods; DPPH, ABTS, CUPRAC and β-carotene bleaching method in both water and methanolic extracts. Total phenolic content and phenolic profiles were determined by FCR (Folin-Ciocalteu reagent) method and HPLC, with respect. Additionally mineral contents and some physicochemical properties were analyzed. The antioxidant activities obtained from aqueous extract as 0.56 mmol TR/g-sample for CUPRAC, 97.02% for β-carotene bleaching method, 88.65% for ABTS and 86.69% for DPPH. For the methanol extraction antioxidant activities recorded as 0.99 mmol TR/g-sample for CUPRAC, 95.21% for β-carotene bleaching method, 93.43% for ABTS and 85.21% for DPPH. Total phenolic compound level was determined as 929.27 mg GAE/100 g in aqueous extract and that was found to be higher than methanolic extract. The most dominant phenolic compounds in the R. pimpinellifolia were detected as chlorogenic acid, vanillic acid and gallic acid. The dominant minerals found in this wild fruit were K (12.1688 mg/ml), P (1.3429 mg/ml) and Mg (1.1926 mg/ml) whereas Cr (0.00001 mg/ml) was minimum. Consequently, black rosehip (R. pimpinellifolia) fruit can be suggested to be very good natural nutrient source due to its high content of phenolic compounds and minerals and important antioxidant activity and phenolic.
