ABSTRACT
Similipal Biosphere Reserve (SBR) is only biosphere reserve of
Odisha, hub of untamed wild phytoresources, where wild cucurbits play a
significant role against the microbial infections. Antimicrobial resistance is
a global burning problem. Keeping this in view, four wild cucurbits (Trichosanthus tricuspidata, Diplocyclos
palmatus, Cucumis melo and Trichosanthus cucumerina) were selected as per their
sound therapeutic in SBR. Estimation of
MIC (minimum inhibitory concentration) values of said plant parts (leaves, fruits,
root) was carried out against Streptococcus
mutans (MTCC 497), Streptococcus
pyogenes (MTCC 1926), Vibrio cholerae
(MTCC 3906), Shigella flexneri (MTCC
1457) and Salmonella typhi (MTCC
1252). The results revealed that MIC of
selected wild cucurbits plant parts extracts showed significant antibacterial
activity. Out of the extracts, methanol extract of T. tricuspidata fruits exhibited highest inhibitory effect (200 µg/mL) against MTCC 1936 and
MTCC 497.
