Comparative analysis of in vitro antibacterial activity of extracts of Viola patrinii on pathogenic microorganisms

Abstract

The antibacterial activities of hexane (H), petroleum ether (PE), acetone (AC), choloroform (C), ethanolic (E) and water (W) extracts of whole plant (1mg/ml) of Viola patrinii were determined against wide variety of pathogenic bacteria. The extracts were tested against various bacteria’s like Escherichia coli (EC), Staphylococcus aureus (SA), Staphylococcus pyogens (SP), Bacillus subtilis (BS), Klebsiella pneumoniae (KP) and lactococcus (LC) by well diffu- sion method. Minimum inhibitory concentration (MIC) and Minimum lethal concentration (MLC) values of each extract were determined. It is concluded that ethanolic extract of whole plant of Viola partinii exhibited significant antibacterial activity. These findings established the potential of the plant Viola partinii as an effective antibacterial agent. However, further studies are needed to evaluate active compounds and probable medicinal benefits in chemotherapy among humans.
