A Comparative Analysis On The Efficacy Of Different Plant Part’s Extract Of Lantana Camara L. And Lantana Indica L. Against Certain Gram-Positive And Gram-Negative Bacteria

Abstract

It has been demonstrated that plants provide great value in the fight against microbial infections due to their antibacterial properties and the growing concern for antibiotic resistance. The goal of this research is to analyze the antibacterial effect of various plant part extracts (stems, leaves, and seeds) of Lantana camara L. and Lantana indica L. Extracts from these plants were tested against two gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus) and two gram-negative bacteria (Escherichia coli and Klebsiella pneumoniae) using the agar diffusion method. The results showed that both species of Lantana stem extracts had the strongest antimicrobial activity, whereas Lantana indica stem extracts had the largest zone of inhibition for Bacillus subtilis. Meanwhile, the seed extracts of both species demonstrated the least antimicrobial activity. This suggests that Lantana species has the potential for development as a source of natural antibacterial agents and pharmaceuticals, thus reducing the use of chemical drugs.
