Résumé
Knautia arvensis, also known as field scabious, is a perennial herb found in European grasslands, as well as parts of Africa and Asia [PMID:30520593].
Contexte
Knautia arvensis (family Dipsacaceae) is a gynodioecious perennial herb typically found in dry meadows, pastures, dry hills, and open woods [PMID:16133196, PMID:30520593]. It exists as a diploid-tetraploid complex with variations in ploidy levels across its geographic distribution [PMID:19196717, PMID:22792207].
Composés actifs
Phenolic constituents isolated from the aerial parts include a new C-6 flavone glycoside, cryptochlorogenic acid, chlorogenic acid, 2-O-trans-caffeoylhydrocitric acid, isovitexin 7-beta-D-glucopyranoside, 7,4'-dihydroxy-5-methoxyflavone-6-C-beta-D-glucopyranoside, 3,5-O-dicaffeoylquinic acid, and 4,5-O-dicaffeoylquinic acid [PMID:22224276]. The plant also contains saponosides [PMID:4994986] and nectar containing carbohydrates and essential amino acids such as valine, isoleucine, leucine, and lysine [PMID:31979080].
Mécanisme d'action
Freeze-dried, ground foliage of Knautia arvensis has been shown to inhibit proteolysis in ruminal digesta, likely through the formation of insoluble tannin-protein complexes [PMID:17445338].
