The study showed that the biological evaluation obtained from the Plant Extracts against types of gram- and gram+ bacteria gave different results depending on the different kind of bacteria except the ethanol extract 48 hours did not show any effectiveness on the tested bacteria. Comparing the inhibition effect, the ethanol extract for 72 hours was the most effective among them. Therefore, we can say
