Abstract
ObjectiveTo evaluate the antimicrobial efficacy of Citrus aurantifolia Linn (CA) against some microorganisms – bacteria and fungus were Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia, Pseudomonas spp, Aspergillus niger, Aspergillus fumigates, Mucor spp and Pencillium. Methods100 μl of 10 mg CA were assessed against eight test microorganisms by agar well Diffusion Method. Gentamicin and Ketoconazole 10 mg/ml were used as standards. A different solvent was used to obtain CA leaf extract by using maceration technique. Results%yield obtained for dried leaf extract of CA with chloroform, ethanol, acetone, petroleum ether and aqueous ethanol was approximately 15%, 18%, 09%, 11% and 24% respectively. Due to its high yield value hydroalcoholic extract of CA was used for estimating the antimicrobial activity and its phytochemical screening. Phytochemical screening of CA plant reveals the presence of Alkaloids, carbohydrates, flavonoids, steroids and tannins. ConclusionsThe study demonstrates that the hydroalcoholic extract of CA leaf exhibit antibacterial activity on Klebsiella pneumonia, Pseudomonas sp, Staphylococcus aureus and antifungal activity among Aspergillus niger, Aspergillus fumigates, Mucor species. These recognized a good support to the use of this plant in herbal medicine and as base for the development of new drugs and phytomedicine.
