For this motive, substitute methods to minimize chemicals are being developed. One of the effective methods is use plant extracts which having natural antimicrobial properties. The aim of this study was to evaluate ethanolic extract of <em>Datura stramonium </em>L. (leaves) and <em>Hippophae rhamnoides  </em>(fruits) against the selected micro-organisms. Results revealed that mean zone of inhibition for bacterial species ranged from 23±0.72 to 27±1.24 mm in case of <em>Hippophae rhamnoides </em>and from 21±0.79 to 30±1.06 mm in case of <em>D. stramonium </em>leaves respectively. For antifungal activity, the inhibition zone ranges from 39.42±1.07 to 47.22±2.11 mm in case of <em>D. stramonium </em>and from 38.42±1.19 to 48.46±2.32 mm in case of <em>H. rhamnoides</em>. However, sensitivity reaction of bacterial and fungal species against each plant extract was also differential. <em>D. stramonium </em>showed highest toxic effect against <em>E. coli </em>(30±1.06 mm)) and <em>Aspergillus flavus </em>(47.22±2.11mm). Whereas, <em>H. rahmnoides </em>showed highest zone of inhibition against bacterial species (<em>B. subtilis </em>27±1.24 mm) and fungal species (<em>R. stolonifer </em>48.46±2.32 mm). Both plant extract exhibited antimicrobial properties, which could be used against micro-organisms.</p> <p> </p>}, number={3}, journal={Biological Sciences - PJSIR}, author={Abbas, Qamar and Batool, Shahina and Khan, Sher Wali and Hussain, Azhar and Din, Saif Ud and Nafees, Maisoor Ahmed and Ali, Shamsher and Faizi, Muhmmad Ali and ullah, Asad}, year={2021}, month={Oct.}, pages={251–255} }
