Additionally, I assessed their <jats:italic>in\u2005vitro<\/jats:italic> antioxidant activity. The gas chromatography\u2010mass spectrometry analysis of the EO revealed a high content of oxygenated monoterpenes (79.86\u2009%), primarily dominated by pulegone (35.11\u2009%), carvacrol (27.36\u2009%), and <jats:italic>neo<\/jats:italic>\u2010dihydrocarveol (4.67\u2009%). The ME was analyzed by liquid chromatography\u2010mass spectrometry to determine its qualitative chemical profile. Four organic acids, eleven phenolic compounds, sixteen flavonoids, nine terpenoids (eight triterpenoids and one diterpenoid), and one coumarin were found in the ME of <jats:italic>ACGL<\/jats:italic>. This extract was found to be dominated by 5,6,4\u2010trihydroxy\u20107,3\u2010dimethoxyflavone (39.30\u2009%), acteoside (30.27\u2009%), nevadensin (7.55\u2009%), isoacteoside (3.08\u2009%) and apiin (3.23\u2009%), and hesperidin (2.73\u2009%). The phenolic (TPC=127.70\u00b11.47\u2005mg gallic acid equivalents\/g of extract) and flavonoid (TFC=85.48\u00b10.12\u2005mg quercetin equivalents\/g of extract) contents of the ME were also assessed. The <jats:italic>in\u2005vitro<\/jats:italic> antioxidant activities of both the EO and ME were evaluated using DPPH, ABTS, and ferrous ion chelating effect assays.
