Chloroform, ethyl acetate and ethanol, which were used for the extraction of Maerua. pseudopetalosa parts, gave nine extracts with different colors, consistencies and extractabilities. Four bacterial strains (Bacillus cereus, Escherichia coli, Staphylococcus aureus and Salmonella typhi, and three fungal species: Aspergillus fumigatus, Aspergillus flavus and Candida albicans) were tested for antimicrobial activities of the extracts. The antibacterial activity was of the limited type (only 11%); while antifungal activity showed considerable variations depending on the type of the extract, the fungus and the duration of the treatment. Tests for secondary metabolites proved the presence of tannins, sterolsL and alkaloids. The detection of sterols, alkaloids, flavonoids and cardiac glycosides were proved by TLC separation in the crude extracts.
