  author={Ira Taneva and Nadezhda Tr. Petkova and Ivan K Dimov and Ivan Georgiev Ivanov and Panteley P. Denev},
  journal={Journal of Pharmacognosy and Phytochemistry},
The aim of the current research was to determine the ascorbic acid content, total tannins and total phenolic content in three extracts (water, 50 % v/v ethanol, 70 % (v/v) ethanol) obtained from dry wild growing rose hip fruits and to evaluate their antioxidant potential by four reliable methods: DPPH, ABTS, FRAP, CUPRAC. The highest ascorbic acid content was observed in 70 % (v/v) ethanol extract – 2404 mg/100 g dw, while the total tannins dominated in the water extracts – 3.86 g/100 g dw. The…
