Abstract
The objective of this work was to determine some bioactive compounds for four different rosehip species (Rosa L.), growing in the East Anatolia region of Turkey. The highest total phenolic, L-ascorbic acid contents and the highest total antioxidant capacity were found in R. canina. The total phenolic, total anthocyanin, total dry matter, and L-ascorbic acid contents and the total antioxidant capacity of the rosehip species ranged from 1081–6298 mg/100 g, 2.43–3.72 mg/100 g, 40.1–56.7%, 24.98–754.48 mg/100 g, and 10.04–97.95 mmol of Trolox equivalent/g (TE/g), respectively. The major organic acid in the rosehip species was found to be citric acid (0.48–1.05 g/100 g).
