Abstract:
Salviae and Plantago species are plants known as having antioxidant effects. The aim of the study was to compare in vitro
the antioxidant capacity of these medicinal plants from two different areas of Romania (Bihor and Arad counties) in order to
use it in the future in the field of pharmacology and medicine. An UV-Vis spectra fingerprint (250-800 nm) of ethanol
extracts from Salviae and Plantago species was recorded in order to establish the maximum absorption, specifically 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 shown, that Salviae species are rich in polyphenols, while Plantago is rich in flavonoids being a good
reason for their association.
