The artichoke (Cynara cardunculus L. subsp. scolymus L.), the cultivated cardoon (Cynara cardunculus var. altilis DC.) and the wild cardoon (Cynara cardunculus var. sylvestris L.) are species widely distributed in the Mediterranean area. The aim of this research was to evaluate the antioxidant properties of seeds from lines of artichoke and cultivated and wild cardoon in both aqueous-organic extracts and their residues by FRAP (Ferric Reducing Antioxidant Power) and TEAC (Trolox Equivalent Antioxidant Capacity) evaluations. Both artichoke and cardoon seeds are a good source of antioxidants. Among artichoke seeds, hydrolysable polyphenols contribution to antioxidant properties ranged from 41% to 78% for FRAP values and from 17% to 37% for TEAC values. No difference between cultivated and wild cardoon in antioxidant properties are reported. Our results could provide information about the potential industrial use and application of artichoke and/or cardoon seeds.
洋蓟（Cynara cardunculus L. subsp. scolymus L.）、栽培刺菜蓟（Cynara cardunculus var. altilis DC.）和野生刺菜蓟（Cynara cardunculus var. sylvestris L.）是在地中海地区广泛分布的物种。本研究的目的是通过FRAP（铁还原抗氧化能力）和TEAC（Trolox等效抗氧化能力）评估，来评价洋蓟、栽培刺菜蓟和野生刺菜蓟品系种子在水-有机提取物及其残渣中的抗氧化特性。洋蓟和刺菜蓟种子都是抗氧化剂的良好来源。在洋蓟种子中，可水解多酚对FRAP值的抗氧化特性贡献范围为41%至78%，对TEAC值的贡献范围为17%至37%。未报道栽培刺菜蓟和野生刺菜蓟在抗氧化特性上存在差异。我们的结果可为洋蓟和/或刺菜蓟种子的潜在工业用途和应用提供信息。
