Seeds and skins from grapes of Vitis vinifera varieties Merlot and Chardonnay and in seeds from grapes of Vitis rotundifolia variety Muscadine were analyzed with HPLC for the major monomeric flavanols and phenolic acids. The contribution of the major monomeric flavanols and phenolic acid to the total antioxidant capacity of grape seeds and skins was also determined. Gallic acid, catechin and epicatechin concentrations were 68, 7, and 69 mg/100 g d. m. in Muscadine seeds, 10, 211, and 303 mg/100 g d. m. in Chardonnay...

Seeds and skins from grapes of Vitis vinifera varieties Merlot and Chardonnay and in seeds from grapes of Vitis rotundifolia variety Muscadine were analyzed with HPLC for the major monomeric flavanols and phenolic acids. The contribution of the major monomeric flavanols and phenolic acid to the total antioxidant capacity of grape seeds and skins was also determined. Gallic acid, catechin and epicatechin concentrations were 68, 7, and 69 mg/100 g d. m. in Muscadine seeds, 10, 211, and 303 mg/100 g d. m. in Chardonnay seeds, and 7, 74, and 83 mg/100 g d. m. in Merlot seeds, respectively. Concentrations of these three compounds were lower in winery byproduct grape skins than seeds. These three major phenolic constituents of grape seeds contributed less than 17% to the antioxidant capacity measured as ORAC. Peroxyl radical scavenging activities of phenolics present in grape seeds or skins in decreasing order were resveratrol > catechin > epicatechin = gallocatechin > gallic acid = ellagic acid. The results indicated that dimeric, trimeric, oligomeric or polymeric procyanidins account for most of the superior antioxidant capacity of grape seeds.
