This study aims to characterize the antioxidant activity of the Agrimonia eupatoria L.
Agrimonia eupatoria infusion (AeI) and its ethyl acetate fraction (AePF) were dissolved in distilled water and the administrated doses were calculated based on the traditionally used doses (extract of 5 g of plant in 150 mL of water), taking into account our yield of the extraction by infusion and by ethyl acetate fractioning process, as well as the conversion into animal doses, according to the FDA (Food and Drug Administration) guidelines, "Estimating the Safe Starting Dose in Clinical Trials for Therapeutics in Adult Healthy Volunteers" .
In the present study, the main polyphenols of Agrimonia eupatoria aerial part infusion were identified, the results demonstrating their contribution for the antioxidant, antiinflammatory, and analgesic activities.
As shown in Table 2, Agrimonia eupatoria infusion (AeI) and its ethyl acetate fraction (AePF) exerted a significant scavenging effect, reacting with the DPPH free radical.
caerulea communities with dry forest edge species of Trifolio-Geranietea covered small patches in dry, sunny sites along the forest-grassland edges and often contained several forest edge species such as Agrimonia eupatoria, Trifolium medium, Origanum vulgare, Melampyrum nemorosum, Solidago virgaurea.
In dry forest edges some species of Trifolio-Geranietea indicated natural transformation towards forest communities, e.g., Trifolium medium and Agrimonia eupatoria were often accompanied by C.
