Abstract
An experiment was conducted to investigate the antimicrobial capacity of water, methanolic crude, ethyl acetate, hexane and butanol extracted samples from the dried leaves of persimmon and date-plum. Four bacterial and a single fungal species were tested in this investigation. Three concentrations of each solvent extracted sample were screened using disc diffusion assay. Leaves extracted ethyl acetate and n-butanol fractions of both Diospyros species displayed higher inhibitory activities against all the microorganisms used. Crude extract of date-plum revealed highest zone of inhibition (57%) against E. coli. Against E. coli, the highest activity exhibited by ethyl acetate extract of persimmon was 54% and date-plum was 55%. The n-butanol extract of both plant species displayed more inhibition (52%) against E. coli and P. aeruginosa. Both E. coli and S. aureus displayed resistance towards n-hexane fraction extracted from leaves of persimmon. Bacterial strain of P. aeruginosa appeared to be absolutely resistant to both aqueous and n-hexane fractions persimmon and date-plum. All leaves extracts of both persimmon and date-plum gave prominent activities against Candida albicans apart from n-hexane fraction of persimmon, where zero activity was noticed. In nutshell, the leaves extracts of date-plum were found more potent then persimmon.
