Description
ABSTRACT
Now days the pathogens microorganisms are very resisted by inorganic compounds. Different organic and aqueous extracts of leaves of Cassia tora L. (caesalpiniaceae) were screened for their antimicrobial activity against three human pathogenic bacteria and two fungal strains by disk diffusion method. The pattern of inhibition varied with the solvent used for extraction and the microorganisms tested. Among these extracts, methanol and aqueous extracts showed significant antimicrobial activity against most of the tested microbes. The most susceptible microorganism was P. aeruginosa (19 mm zone of inhibition in aqueous extract) followed by Candida albicans (7mm zone of inhibition in methanol extract). Preliminary photochemical analysis of different extracts revealed the presence of anthraquinones, carbohydrates, glycosides, steroids, flavonoids, saponins and alkaloids were absent in all the tested extracts.
Key Words: Cassia tora L. Antimicrobial activity, Human pathogens.
