Antibacterial Activity of Economically Important Medicinal Plants in Pakistan Against Different Bacterial Strains.

The emergence of medication resistance and unfavorable side effects from existing antibiotics has prompted the quest for novel antimicrobial agents over the last 2 decades. Plant extracts have been shown to have antibacterial effects in numerous studies. The objective of this study was the evaluation of the antibacterial effect of economically important medicinal plants found in Pakistan. (flowers and leaves), (flowers and leaves), (whole plant), (whole plant), and (whole plant) were used against , and Water and ethanol extracts were obtained from different parts of the plants. To evaluate the antibacterial effect of these plants, qualitative assay agar well diffusion method was performed. The minimum inhibitory concentration (MIC) was determined by the broth micro dilution method. Results revealed that the highest inhibition zone (18 mm) was shown by ethanol extract of flower against . Ethanol extract of plants is best for all 3 tested microbes (, and ). The results concluded that all these plants have abilities to fight against these tested bacteria. Ethanol extract of flower has the highest activity against .
