Abstract: To analyze the antioxidant components and activities of different tissue in varieties of hawthorn, three hawthorn varieties were characterized concerning for their antioxidant capacities and antioxidant compounds such as phenolic, flavonoid, tannin and anthocyanin. Antioxidant capacity was measured using the DPPH, ABTS and reducing power assays. The results showed that the peel of all cultivars had the best antioxidant capacities, reflected the highest content of total phenolics, flavonoids, and anthocyanins found in this part. The peel and pulp of big hawthorn and small hawthorn contained higher total phenolics and total flavonoids. There were positive significant correlations between the total phenolics, total flavonoids and antioxidant activity in different tissues of hawthorn fruits. The results obtained in this study indicated that the peel and pulp of hawthorn had a potential to be used as a natural antioxidant agent.
