The polyphenolic content and antioxidant capacity in the seeds of 11 red grape varieties (five international and six native) widely cultivated in Turkey were investigated. Total phenolic, total flavanol and total polymeric procyanidin content ranged from 79.2 to 154.6, 89.2 to 179.4, and 27.0 to 43.3mg/g seed, respectively. While (+)-catechin (4.71-23.8mg/g seed) was found as main flavanol, galloylated catechin monomer and dimeric procyanidin amounts varied between 2.89-17.2 and 0.97-2.97mg/g seed, respectively. All seed extracts showed remarkable DPPH radical scavenging activity (EC50) and oxygen radical scavenging capacity (ORAC) ranging from 2.71 to 4.62μg/mL and 1425.9 to 3009.2μmol Trolox equivalent/g seed, respectively. With high amount of total phenolic content and antioxidant activity, seeds of Okuzgozu, Papaz Karasi, Ada Karasi and Kalecik Karasi varieties could be evaluated as dietary supplement.
研究了土耳其广泛种植的 11 种红葡萄品种（5 种国际品种和 6 种本地品种）种子中的多酚含量和抗氧化能力。总酚、总黄烷醇和总聚合原花青素含量分别为 79.2 至 154.6、89.2 至 179.4 和 27.0 至 43.3mg/g 种子。虽然（+）-儿茶素（4.71-23.8mg/g 种子）被发现为主要黄烷醇，但没食子酰化儿茶素单体和二聚原花青素的含量在 2.89-17.2 和 0.97-2.97mg/g 种子之间变化。所有种子提取物均表现出显著的 DPPH 自由基清除活性（EC50）和氧自由基清除能力（ORAC），范围分别为 2.71 至 4.62μg/mL 和 1425.9 至 3009.2μmol Trolox 当量/g 种子。Okuzgozu、Papaz Karasi、Ada Karasi 和 Kalecik Karasi 品种的种子具有高含量的总酚含量和抗氧化活性，可作为膳食补充剂进行评估。
