Cholinesterase and microbial inhibitory activities of Tetrapleura tetraptera
Journal Title: Journal of Applied and Natural Science - Year 2012, Vol 4, Issue 2
Abstract
The cholinesterase and microbial inhibitory activities of different parts of Tetrapleura tetraptera plant were evaluated due to their local applications. The cholinesterase results revealed that the extracts showed some levels of inhibitory effects depending on the solvents used. Tetrapleura tetraptera leaves had better inhibitory effects with maximum inhibitory activity of 70.0% at a concentration of 1.00mg/l for the water extract. Tetrapleura tetraptera bark showed highest inhibitory effect of 71.05% and (84.34%) for the ethanol and chloroform extracts at concentrations of 0.5mg/l and 1.0 mg/l respectively. While for petroleum ether, T. tetraptera bark recorded 74.34% inhibitory effect at concentration of 2.0 mg/l and also showed continuous increase in inhibitory activity as the concentration increases for aqueous methanol. The results of the antimicrobial activities showed that among all the test organisms, the ethanol and water extracts of the leaves, stem, bark and root of the plants had promising activity against Escherichia coli, Staphylococcus aureus, Proteus mirabilis, Pseudomonas aeruginosa and Klebsiella pneumonia bacteria and Aspergillus fumigatus and Rhizopus species fungi. There was no activity shown by the ethanol and water extracts of the parts of the plants with Fugarium oxysporum, Penicillium chrysogenum and Mucor species fungi. The bacteria strains were more sensitive to the tested extracts than the fungi strains.
