The results of the comparison showed that there is no difference. F. simplicissima Lour has a woody stem, tap-root, simple leaves, board of leaves are not lobed, edges of leaves are serrated. The anatomy of nutrient organs of the plant by double staining method showed cork, phylum, soft tissue, libe and xylem. The similarity between the morphology and anatomy of the plant is the basis for increasing the biomass of biologically active substances in the plant. The pure ethanol extract obtained by the Ultrasound-assisted extraction method from F.simplicissima Lour was resistant S. aureuns from 22.67 mm (extraction 2nd) to 23.67 mm (extraction 1st). Correspondingly, P. aeruginosa from 18,00 mm to 20,33 mm and C. freundii from 18.33 mm to 19.67 mm. When the extract concentration was reduced to 50% the antibacterial ability was reduced to 50%, the antibacterial ability was reduced and no antibacterial ability when the extract was reduced by 25%.
