Chemical Composition and Biological Properties of <i>Achillea cucullata</i> Extracts from Leaves and Flowers
Abstract
Achillea cucullata is a perennial herbaceous plant that has a long history of medical use in many cultures. The present research focuses on the biological activity and therapeutic potential of A. cucullata, namely its antibacterial and anticancer properties. While previous studies have shed light on the cytotoxic and antibacterial capabilities of Achillea cucullata aerial parts, there is still a considerable gap in knowledge concerning the anticancer potential of leaf and flower extracts. A. cucullata’s leaves and flowers were extracted using methanol. The total phenolic and flavonoid contents were evaluated. The antioxidant, cytotoxic, and antibacterial properties were evaluated against both Gram-positive and Gram-negative bacteria. The Gas Chromatography–Mass Spectrometry (GC–MS) analysis of A. cucullata leaf and flower extracts showed numerous amounts of bioactive components, including carvacrol, a TBDMS derivative; 2-Myristynoyl-glycinamide, acetylaminobenzothiazol-2-yl)-2-(adamantan-1-yl); Isolongifolol; (3E,10Z)-Oxacyclotrideca-3,10-diene-2,7-dione; and 3-Heptanone, 5-hydroxy-1,7-diphenyl. The extract has a high level of phenols and flavonoids. Cytotoxicity studies found that A. cucullata leaves and flowers had dose-dependent toxicity against MCF-7 and HepG2 cancer cell lines, with flowers being more effective. Apoptotic genes (caspase-3, 8, 9, and Bax) were upregulated in treated MCF-7 and HepG2 cells, whereas anti-apoptotic genes (Bcl-xL and Bcl-2) were reduced. Antibacterial screening revealed significant activity against both Gram-positive and Gram-negative pathogens. Overall, the research highlights the varied therapeutic potentials of A. cucullata, adding to the knowledge of plant-derived extracts in lowering disease risks. Future research should concentrate on in vivo studies to assess the effectiveness and safety of these substances.
