Bacterial wilt caused by Ralstonia solanacearum
is a soil borne disease affecting several plant species of
different genera. Management of this disease with various
strategies provided limited success. Plant product in the
management of bacterial wilt is one of the minimum
explored areas. In the present study attempts were made to
exploit the antibacterial properties of the locally available
plant species for the inhibition of R. solanacearum and also
to characterize the phytochemicals in two of the promising
plant species by Gas Chromatography–Mass Spectrometry
(GC–MS). Thirty-two plants species were screened for
their antimicrobial activity against R. solanacearum using
eight organic solvents. Out of the 264 tested extracts 123
showed zones of inhibition under in vitro condition. It was
observed that alcohol extracts showed better activity
against R. solanacearum as compared to other solvents.
Two plant species viz. Garcinia indica and Tamarindus
indica were highly inhibitory to the pathogen. The phytochemical
analysis indicated the presence of saponins, terpenoids,
alkaloids, flavonoids and tannins in the extracts.
Fractions from solvent–solvent partitioning indicated that
alcohol based fraction (Fraction III) was inhibitory to the
pathogen. GC–MS analysis of Fraction-III revealed the
presence of phytoconstituents viz. 4H-pyran-4-one,2,3-dihydro-
3,5-dihydroxy-6-methyl and 2-Furancarboxaldehyde,
5 (hydroxymethyl) in G. indica; butanoic acid, and myo-inositol, 4-C-methyl in T. indica. The present study is
the first report on the use of G. indica and T. indica in
inhibiting R. solanacearum and the antimicrobial constituents
of the extracts.
