Abstract
O combination of 50:50 (v/v), extraction time of 60 min, and HCOOH concentration of 0.5% (v/v). The highest TPC and antioxidant activity were observed in quince (281-510 mg GAE/100g and 109-395 mg AAE/100g) whereas the lowest were measured in European crab apple (55.9-70.0 mg GAE/100g and 20.1-43.2 mg AAE/100g). Bilberry exhibited the highest TMA content (346 mg CGE/100g). Overall, our results showed that these wild fruits could be a good source of natural antioxidants for the local residents.
