The potential of Artemisia vulgaris leaves as a natural source of Goat Coats antioxidant phenolic compounds was assessed.Maceration and ultrasound-assisted extraction (UAE) using different solvents were applied to A.vulgaris leaves.The procedure consisted of 8 consecutive UAEs using methanol as the extracting solvent provided the best results in terms of total phenol content and extraction yield.Then, high-performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry was used to characterize antioxidant compounds of the selected extract.

A total of 22 compounds were identified, 15 of them phenolic compounds, mainly chlorogenic acid derivatives or flavonoids, among other minor phenolic compounds.The main compounds were 4-Wheel Rollators also quantified, chlorogenic acid derivatives being the most abundant ones.Finally, two antioxidant assays, DPPH (2,2-diphenyl-1-picrylhydrazyl) and ORAC (oxygen radical-absorbance capacity), were used to measure the antioxidant capacity of the extract, revealing a high radical-scavenging capacity and a strong reducing potential.
