AbstractVicia ervilia is an ancient crop from the Mediterranean Region. It may represent a useful source of proteins for food and animal feed, as well as bioactive components. Seed samples from 39 populations of V. ervilia have been analyzed. Polyphenol contents ranged from 0.09% to 0.19%. Luteolin, kaempferol, apigenin, and quercetin were the major aglycones. The total free amino acid content of the seeds was 0.05% to 0.19% in which canavanine represented 9% to 22%. The protein content was 24.1%. The amino acid composition indicated a high content in acidic amino acids and a deficit in sulphur amino acids. V. ervilia seeds proved to be a good substrate for the preparation of protein isolates. The seed extracts inhibited the proliferation of Caco‐2 colon tumor cells, simultaneously, exerting antioxidative effects. Hence, seeds of V. ervilia could represent a source of high‐value food and feed components, as well as functional components.
