The present study is an investigation on the antibacterial and antifungal activity of the extracts of ethno botanically important plant Abutilon fruiticosum Gill & Perr. in different polar and non-polar solvents. The zone of inhibition and minimum inhibitory concentration (MIC) were recorded against four different bacterial (Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa) and two fungal strains (Aspergillus niger, Aspergillus oryzae). The results revealed that the plant had reasonably good antimicrobial potential. The root and stem extracts showed maximum zone of inhibition against bacterial strains, i.e. 47±0.14mm, 40±0.11mm and 38±0.28mm while the n-Hexane fruit and flower extracts exposed the best zone against both of the fungal strains. The ethanol extracts when subjected to the qualitative minimum inhibitory concentration using six different extract concentrations, indicated the most resistant values, i.e. 1.25mg/ml against bacterial strains and 2.5mg/ml against fungal strains.
