Phytochemical Profile and Anticancer Activity of Achillea conferta Leaf Extracts: Insights Into Antioxidant Properties

Abstract This study explores the phytochemical composition and biological potential of extracts from Achillea conferta leaves, specifically hydroethanolic extract (HE), total flavonoid extract (TFE), and glycoside flavonoid extract (GFE). Phytochemical screening of HE revealed significant concentrations of phenolic compounds, flavonoids, and tannins, quantified as 48.36 µg GAE/mL extract, 32.40 µg QE/mL extract, and 4.85 µg TAE/mL extract, respectively. High‐performance liquid chromatography identified key flavonoids in TFE and GFE, including catechin, epigallocatechin, hesperidin, myricetin, rutin, isorhamnetin, and luteolin. Antioxidant activities were
