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.
