The sarunashi berry is an edible fruit form a cultivar group of the Actinidia species. In this study,the total polyphenol content and antioxidant properties of its peel, seed and pulp were analyzed and compared with those of the kiwifruit,which is the most common commercially available cultivar group of this species. Sarunashi peel showed the highest antioxidant potential on the basis of DPPH radical-scavenging assays. The main active constituents of the peel,as determined by HPLC were quercetin-3-galactoside and procyanidin B1, both of which showed high radical-scavenging activity. These two constituents may contribute to the antioxidant properties of sarunashi peel. Accordingly, it can be considerd that the fruit may serve as a significant source of antioxidants.
