In order to investigate the utilization of wild grape by-products, isolation of proanthocyanidin from the wild grape seed (Vitis amurensis) and its antioxidant capacities were examined. 70% acetone crude extract of the wild grape seed was fractionated. The ethyl acetate fraction was applied to Sephadex LH-20 column chromatography, which was eluted with 50%, 75% methanol, and 75% acetone, respectively, and 9 fractions were collected, finally. Their proanthocyanidin characteristics and contents were investigated by vanillin-$H_2SO_4$ and BuOH-HCl methods. The Fr. 5 has the highest proanthocyanidin content ($86.00{\pm}6.74$ g%) among all the fractions. Fr. 6-2 was identified as (+)-catechin by LC-MS analysis. The antioxidant activities of the proanthocyanidin were evaluated by total phenolic contents, DPPH radical scavenging, and FRAP assays. Fr. 8 shows the strongest antioxidant activities with high proanthocyanidin content. The wild grape seed containing fairly high amounts of proanthocyanidin could be utilized as a natural antioxidant material.
