    Studysummary This study evaluated the wedelolactone content and antimicrobial activity of Eclipta alba and Wedelia chinensis extracts, finding a potential relationship between the concentration of wedelolactone and their in vitro antimicrobial effects against several pathogenic bacteria and yeast. Our plain-language summary of this paper — not a Tressless recommendation.
    The study found that Eclipta alba contains a higher wedelolactone content (0.040% w/w) than Wedelia chinensis (0.031% w/w), making it a more efficient source for extraction. However, Wedelia chinensis demonstrated superior antimicrobial activity, possibly due to the synergistic effects of other phytochemicals. Both plants were effective against pathogens such as Staphylococcus aureus, E. coli, Pseudomonas aeruginosa, and Candida albicans, with methanol identified as the most effective extraction solvent. The research suggests the potential of these plants in developing antimicrobial agents.
