Natural
products are of paramount importances for sustainability of life in this modern
era. In most of developing countries, to achieve sufficiency in supply of
adequate food and medicine for rural and tribal people have been a challenge.
It is more so in remote areas. There is continuous search for natural products
for food and medicines from biodiversity. Biodiversity provides not only
uncountable and untamed resources of food and medicines but also provide rich
resources of natural products. Among them, wild tuber crops are significant. They
are rich in energy supplemented metabolites and are well known as food during
normal and off agricultural seasons. Many of them are also sources of natural
antibacterial agents. Rural and tribal communities use them against different microbial
infections. Keeping this in view, an attempt has been made to screen the
secondary metabolites present in the plants parts of Dioscorea oppositifolia and to analyse the antibacterial potential
of plant extracts. Results revealed that the plant parts of this wild tuber
crop are rich with diverse bioactive compounds like tannin, saponin, flavonoids
etc. The antibacterial activity exhibited significant inhibitory action against
some selected bacterial strains (MTCC 1252- Salmonella typhi, MTCC 1457-
Shigella flexneri, MTCC 1926 - Streptococcus pyogenes, MTCC 497- Streptococcus
mutans and MTCC 3906- Vibrio cholerae). Present study highlights the
antibacterial importances of this wild tuber crops and justifying the tribal
claims as well as sound natural antibacterial agent.
