Abstract：
Legumes, one of the first crops of humanity, inherently constitute a staple nutritional source for mankind, attracting significant research attention that has been afforded to the development of numerous cultivars. The study herein concerns the exploitation of the nutritional and bio-functional content of beans harvested from eleven Greek cultivars belonging to five different species, namely Cicer arietinum L., Pisum sativum L., Vicia faba L., Lens culinaris L., and Phaseolus vulgaris L. The final goal is to define their varietal identity and correlate their phytochemical content with their potential utilization as functional foods and/or feed of high nutritional value. In this respect, their extracts were screened against the presence of 27 fatty acids and 19 phenolic compounds, revealing the presence of 22 and 15 molecules, respectively. Specifically, numerous fatty acids were detected in significant amounts in all but C. arietinum extract, while significant polyphenolic content was confirmed only in P. vulgaris. Among individual compounds, linoleic acid was the major fatty acid detected in amounts averaging more than 150 mg/g, followed by oleic acid, which was present as a major compound in all extracts. Among the nine polyphenols detected in P. vulgaris, the molecules of genistein (3.88 mg/g) and coumestrol (0.82 mg/g) were the most abundant. Their antioxidant properties were evaluated through DPPH and FRAP assays, which were highlighted as most potent in both tests of the V. faba extract, while C. arietinum was determined as totally inactive, indicating a potential correlation between the phenolic content of the plant species and antioxidant activity. These results are indicative of the significant advances achieved for the cultivars investigated and reveal their important role as nutritional crops for human and animal consumption.
摘要：
豆类,人类最早的庄稼之一，本质上是人类的主要营养来源，吸引了大量的研究关注，已经给予了许多品种的发展。本文的研究涉及从属于五个不同物种的11个希腊品种收获的豆类的营养和生物功能含量的开发，即CicerarietinumL.，PisumsativumL.,维西亚·法巴·L,CulinarisL.,和菜豆L.最终目标是确定它们的品种身份，并将它们的植物化学物质含量与它们作为高营养价值的功能食品和/或饲料的潜在利用相关联。在这方面,对它们的提取物进行了27种脂肪酸和19种酚类化合物的筛选，揭示了22和15个分子的存在，分别。具体来说,除了C.arietinum提取物外，在所有其他物质中都检测到了大量的脂肪酸，而仅在普通P中证实了显着的多酚含量。在单个化合物中，亚油酸是检测到的主要脂肪酸，平均含量超过150毫克/克，其次是油酸，它是存在于所有提取物的主要化合物。在普通P中检测到的9种多酚中，染料木素(3.88mg/g)和香豆雌酚(0.82mg/g)分子含量最高。通过DPPH和FRAP测定评估了它们的抗氧化性能，在两种蚕豆提取物的测试中都被强调为最有效的，而C.arietinum被确定为完全不活跃，表明植物物种的酚类含量与抗氧化活性之间存在潜在的相关性。这些结果表明所研究的品种取得了重大进展，并揭示了它们作为人类和动物消费的营养作物的重要作用。
