Bahawalpur region is situated in the southern Punjab province in Pakistan. Present study was done to evaluate the biological potential of the methanol and n-hexane extracts of two species of Bahawalpur i.e., Dichanthium annulatum and Ochthocloa compressa belonging to family Poaceae. Phytochemical studies revealed that various secondary metabolites were strongly present in the methanol extracts of both species. Maximum phenols (263.345±16.35 mg GAE/g) and flavonoids (28.147±0.32 mg QE/g) contents were detected in the methanol extracts of O. compressa species. Antioxidant potential of plants was determined via free radical scavenging assays and the antimicrobial assays were performed using agar disc diffusion method. Results revealed maximum antioxidant potential in both extracts of O. compressa species as compared to the D. annulatum. Similarly, in case of antimicrobial assay, maximum inhibition zones were formed by the extracts of O. compressa against most of the tested bacterial and fungal strains. However, S. typhi, W. anomalus, A. niger and F. oxysporum were revealed as the most resistant strains and L. monocytogenes, B. spizizenii and A. flavus were revealed as the most sensitive strains. Overall, extracts of O. compressa showed significant biological potential as compared to the D. annulatum plant extracts. Hence, its crude extract can be used in pharmaceutical industries to cure various infectious diseases caused by resistant microbes.
