In Vitro Antibacterial Activity of Flower Extract of Leucas Indica

Abstract

İn this study, the antimicrobial activities of methanol extracts of flowers of Leucas indica was investigated by using agar well diffusion method against selected ten bacterial species (Pseudomonas (MTCC 424), Corynebacterium (MTCC 1349), Spingomonas (MTCC 6362), Bacillus subtilis (MTCC 441), Bacillus licheniformis (MTCC 429), Bacillus coagulans (MTCC 5856), Streptococcus (MTCC 9724), Klebsiella pneumonia (MTCC 452), E. coli (MTCC 443), and Staphyloccus (MTCC 3160).  Among the ten bacterial species studied, the flower extract at concentrations of 20µg and 40µg showed antimicrobial activity against Klebsiella pneumonia, E. coli, Streptococcus, Bacillus subtilis, Spingomonas, Staphyloccus and Corynebacterium respectively.
