Antimicrobial activity refers to a plant's ability to inhibit or kill microorganisms such as bacteria, fungi, and other pathogens, typically through bioactive compounds like alkaloids, flavonoids, and essential oils. This natural defense mechanism is a key component of plant immunity, helping species resist infection and disease in their environment. Studying these properties also drives research into plant-derived compounds as potential sources for natural antimicrobial agents and treatments in medicine and agriculture.
Researchers tested three medicinal plants used in traditional skin disease treatment and found that methanol extracts were the most effective against bacteria and fungi, suggesting these plants contain active compounds worth exploring for modern topical treatments.
1
Methanol extracts outperformed ethanol, ethyl acetate, and water extracts in antimicrobial activity against all tested strains
2
All three plants tested positive for secondary metabolites including phytoconstituents active against skin pathogens
3
Agar disc diffusion testing confirmed activity against three bacterial and three fungal strains associated with skin disease
