| Abstract | ||
| The inhibition activity for the aqueous and alcoholic extracts of Hibiscus sabdariffah being studied by the wells method on some microorganisms such as Staphelococcus aureous, Streptococcus epidermidis, Serratia marcesens, Proteus vulgaris, Enterococcus fecalus, Klebsiella sp, Candida albicans, Asparaglas niger. Escherichia coli, Salmonella typhi, The results also revealed that, the aqueous and alcoholic extracts of Hibiscus sabdariffah had inhibition effects for all microorganism, the cold aqueous showed the higher inhibition than the hot and alcoholic extracts of the plant on Serratia marcesens, Escherichia coli, Enterococcus fecalus at concentration (25,50,75,100)%, The minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) were determined for the plant extract. The results showed that the (MIC) value of all plant extract were (10, 2.5) % on Serratia marcesens, Escherichia coli respectively, were the value of (MBC) was (1.25, 5) % for the same bacteria | ||
