Antimicrobial activity of Alo e v e ra (L.) Burm. f. against pathogenic microorganisms

Plants play a major role in all the traditional system of medicine. Plants contain the rich source of natural products like vitamins, minerals and other immune-modulators. Most of which have been used for human welfare especially to cure disease caused by pathogenic microorganisms without any side effects. The present study was conducted to determine the antimicrobial activity of Aloe Vera juice with different solvents viz; hexane, ethyl acetate, petroleum ether and ethanol against Gram positive bacteria (B. subtilis, S. aureus), Gram negative bacteria (E. coli, K. pneumoniae, P. aeruginosa). The disc diffusion method was used to test the antimicrobial activity. The result showed that more antimicrobial activity in ethyl acetate (1 – 9 mm) and ethanol extract (7 – 12 mm). The least inhibitory effect on petroleum ether extracts was 2 mm. This study was also estimate the amount of minerals present in fresh Aloe Vera juice by Atomic Absorption Spectroscopy. This is important to
