Chromolaena odorata, or Siam weed, is an invasive plant species that inhibits crop growth. Ethanolic extracts of C. odorata were assessed across various plant parts (roots, stems, leaves, and flowers) to compare their phenolic and flavonoid contents as well as their antioxidant and antibacterial activities. Results revealed that all samples, with particular emphasis on the leaf extracts, contained significant amounts of phenolic and flavonoid secondary metabolites. The ethanolic extracts of C. odorata exhibited strong antioxidant and antibacterial properties against gram-positive and gram-negative bacterial strains. This comprehensive methodology provides an alternative strategy for inhibiting pathogenic bacteria and indicates potential medicinal applications utilizing plantbased natural remedies.
