There were significant differences in the three extracts against Escherrichia coli. Whereas in Staphylococcus aureus there was a significant difference between dichloromethane extract and ethylacetate extract, and for hexane extract to dichloromethane extract and ethyl acetate extract there was no significant difference (having the same inhibitory power)
