EVALUATION OF ANTIMICROBIAL SCREENING OF BARKS & LEAVES EXTRACT OF ALBIZIA LEBBECK

ABSTRCT Albizzia lebbeck belonging to the Leguminosae family has been investigated for antimicrobial activities. The powdered stem bark & leaf was extracted with methanol. The concentrated extract was then partitioned with pet-ether, carbon Tetrachloride and chloroform. The pet-ether, carbon tetrachloride and chloroform soluble fractions of the crude methanolic extract of this plant were subjected to microbiological investigation by the disc diffusion method. The results compared with a standard Antibiotic, kanamycin. The pet-ether and chloroform soluble fractions showed moderate to strong antimicrobial activity having the zone of inhibition range from 8.66±0.4mm to 10.66±1.24mm and 8.5±0.81mm to 10.66 ±1.2mm respectively, whereas mild to moderate inhibitory activity was found by carbon tetrachloride fractions and methanol soluble fraction having the zone of inhibition range from 8.33±0.47mm to 10±0.51mm and 8.66±0.1.2mm to 9.66±0.94mm respectively. Aqueous soluble fraction showed no antimicrobial activity against the tested microorganism.
