CHOLINESTERASE AND BACTERIAL INHIBITORY ACTIVITIES OF STACHYTARPHETA CAYENNENSIS

The cholinesterase and bacterial inhibitory activities of the leaves and stem of Stachytarphetacayennensis were evaluated due to their local applications. The results revealed that the extracts of Stachytarphetacayennensis leaves (SCL) and stem (SCS) assessed for their acetyl cholinesterase inhibitory activities showed that all the extracts had some levels of inhibitory effect depending on the solvents used. The result of bacterial inhibition showed that among all the test organisms screened, the ethanol and water extracts of leaves and stem of the plant had promising activity against Escherichia coli, Proteus mirabilis, Pseudomonasaeruginosa and klebsiella pneumonia bacteria. There were no activity shown by the ethanol and water extracts of the parts of the plants with Staphylococcus aureus. The ethanol and water extracts of the leaves had the highest zone of inhibition of 14 mm against Proteus mirabilis and Escherichia coli and klebsiella pneumonia respectively.
