In order to provide information for the further application of Aquilegia oxysepala in food and pharmacy industries, the antioxidant activity of A. oxysepala was investigated in this work by different antioxidant assays. The results showed that the IC 50 of A. oxysepala to scavenge 1,1‐Diphenyl‐2‐picrylhydrazyl radical 2,2‐Diphenyl‐1‐(2,4,6‐trinitrophenyl)hydrazyl radicals, hydroxyl radicals, superoxide anion radicals and hydrogen peroxide was 25.79, 31.50, 18.59 and 41.09 µg/mL, respectively.PRACTICAL APPLICATIONS Aquilegia oxysepala , a traditional Chinese medicine, has been used as food supplement and medicine for thousands of years in China. However, its antioxidant activity is still unknown. In this work, the contents of flavonoids and phenols in A. oxysepala and its antioxidant activity were investigated. The results revealed that the extract of A. oxysepala mainly consisted of flavonoids and had good capacity of scavenging 1,1‐Diphenyl‐2‐picrylhydrazyl radical 2,2‐Diphenyl‐1‐(2,4,6‐trinitrophenyl)hydrazyl radicals, hydroxyl radicals, superoxide anion radicals. This result may provide some useful information for the further application of A. oxysepala for food preservation as well as tonic supplement.
