Laura Vicaș, Alin Teușdea, Simona Vicaș, Eleonora Marian, Jurca Tunde, Mariana Mureșan, Felicia Gligor. Assessment of antioxidant capacity of some extracts for further use in therapy. Revista, 63(2), p. 267 –, 2015.

Rezumat: Salvia and Plantago species are plants known as having antioxidant effects. Aim of the study was to evaluate the antioxidant activity of these plants using a comparative study of two sources from two different areas of Romania. Through their association it can achieve a formula of nutritional supplements with cellular protective role. Plant extracts were drawn the UV- VIS spectrum to highlight the areas that absorbs the various bioactive compounds. The bioactive compounds from those two extracts, polyphenols types were determined by the Folin-Ciocalteu method, and the total flavonoids have been determined through a spectrophotometric method.
Antioxidant capacity of the extracts was evaluated by the following methods
DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2'-Azinobis [3-ethylbenzothiazoline-6-sulfonic acid]-diammonium salt) and FRAP(the Ferric reducing antioxidant power). The results have demonstrated that Salvia species are rich in polyphenols, while Plantago are rich in flavonoids being an good argument for their association

Cuvinte cheie: antioxidant, polifenoli, Plantago sp., Salviae sp.
