摘要

The phytochemical constituents and antimicrobial properties of the aqueous extract of?Cassia arereh?stem-bark were evaluated. The extract was subjected to qualitative chemical screening of active chemical constituents and disc diffusion method was performed to determine the antimicrobial properties. The results revealed the presence of tannins, phlobatannins, carbohydrate, saponin, flvonoids, terpenes and steroids while anthraquinones, alkaloids and cardiac glycosides were not detected. The extracts (100, 200, 400 and 800 mg/ml) inhibited the growth ofStaphylococcus aureus, Bacillus subtilis, Salmonella typhi, Pseudomonas aerogenosa?and Enterobacter species. However,?Escherichia coli, Klebsiella pneumoniae, Corynebacterium pyogenes?and?Candida albicans?were resistant. The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) values were 50mg/ml for?S. aureus?and?B. subtilis, and 100 mg/ml for?P. aeurogenosa. It was concluded that the aqueous extract of?C. arereh?stem-bark contained active principles having antibacterial properties and thus support the folkloric use of the plant.
