Rosa davurica Pall., a useful Rosa species for functional rose hip production with high content of antioxidants and multiple antioxidant activities in hydrophilic extract

·Content of ascorbic acid and polyphenols was compared in nine Rosa species/cultivars.·Antioxidant activities against naturally-occurring ROS were determined using ESR–ST.·Hips from R. davurica had quite high content of antioxidants and antioxidant activities.·Hips from ‘Consared’, a progeny of R. davurica, also had high antioxidant abilities.·Content of ascorbic acid and polyphenols correlated with the activities scavenging ROO▪ and 1O2.
