Aishwarya N. Kapse* and C. J. Chandekar
ABSTRACT
The crude extract from the leaves of Callistemon Lanceolatus traditionally used in Indian system of medicines were screened against Escerichia coli NCIM 2931, Proteus vulgaris NCIM2857, Pseudomonas aeruginosa NCIM5029, Staphylococcus aureus MTCC 96, Bacillus cereus NCIM2155, Bacillus subtilis NCIM 2063 and Bacillus megaterium NCIM 2087 by using agar well diffusion method. Callistemon Lanceolatus crude extract showed significant activity against Gram positive organisms. Zone of inhibition of the extract compared with the standard antibiotics. Fresh leaves juice is active against all organisms. E. coli, P. vulgaris, P. aeruginosa, S. aureus, B. cereus, B. subtilis and B. megaterium. Crude extract active against S. aureus. Methanol extract only active against gram positive organisms. Chloroform extract and petroleum ether extract active against B. megaterium and S. aureus. Petroleum and chloroform ether extract are not active against B. cereus and B. subtilis.
Keywords: Solvent extracts, Antimicrobial activity, Agar well diffusion method.
