| Abstract | ||
| A flavonoid compound was isolated from oak plant (Quercus infectoria oliv.) (Fagaceae) stem barks using ethanol alcohol as a solvent, the isolated compound was identified using conventional characterization methods, such as Thin Layer Chromatography(TLC),Ultraviolet-Visible (UV-Vis) and Fourier transform infrared spectroscopy(FT-IR), as well as, some biochemical assays using color reagents. Antibacterial activity of extracted flavonoid was carried out against two types of reference strains bacteria: which are Gram positive bacteria (Staphylococcus aureus ATCC 25923) and Gram negative ( Escherichia coli ATCC 25923), the results shows that the extract of oak barks has good a antibacterial growth activity in which gram positive bacteria are more susceptible to the oaks extract than Gram negative (31 mm and 19mm, respectively). | ||
