Grape seeds were extracted in 70% acetone solution for 12 hr. The total phenolic content of the extracts ranged from 16.71 to 28.60 mg/100 g. The proanthocyanidin content ranged from 18.36 to 55.30 mg/100 g. The Jaok cultivar had the highest total phenolic and proanthocyanidin content, and showed the strongest antioxidant activity in the FRAP and DPPH assays. The total phenolic and proanthocyanidin content of grape seeds was correlated with their antioxidant capacities (r > 0.92). Acetone extracts of grape seeds could be effective antioxidant materials.Read More
