Abstract

In the present work we evaluated the antibacterial activity of Indian plant Viola odorata used in medicine system of against the pathogenic microorganisms. The series extracts of Viola odorata (whole plant) showed strong antimicrobial activity against all test microorganisms (Shigella flexneri, Staphylococcus aureus , Salmonella typhi, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus vulgaris, Enterobacter aerogenes, Aspergillus niger , Candida albicans, Trichophyton rubrum). All the extracts highly affected the activity of bacteria and fungi. Extract of chloroform, methanol and distilled water was show the best activity against all test microorganisms The maximum efficacy of Petroleum ether extract A2 (100mg concentration) was against Candida albicans (I.Z.-11mm), the maximum efficacy of benzene extract A1 (50mg concentration) was against Trichophyton rubrum (I.Z.-10mm), the maximum efficacy of chloroform extract A4 (200mg concentration) was against Salmonella typhi (I.Z.-16mm), The maximum efficacy of ethyl acetate extract A1 (50mg concentration) was against Candida albicans (I.Z.-20mm), whereas no activity against Proteus vulgaris, Klebsiella pneumoniae and Pseudomonas aeruginosa, have been screened. The maximum efficacy of methanol extract A4 (200mg concentration) was against Staphylococcus aureus (I.Z.-21.33mm), The maximum efficacy of distilled water extract A5 (250mg concentration) was against Salmonella typhi (I.Z.-15mm) have been screened. The results reveal that the use of extracts of this plant may be effective in providing an alternative and effective method to eliminate the pathogens without producing much toxicity compared to the present antibiotics.
