Abstract :

Spices are key ingredients of Indian food as it enhance flavour of the food. Apart from this, they have antimicrobial and preservative properties too. In this study, the antibacterial activity of n-hexane and water extracts of Zingiber officinale (ginger) was evaluated against Escherichia coli and Bacillus subtilis. Different concentrations of both the extracts were tested for studying dose dependent pattern of antibacterial activity of the ginger extract. Results indicated that Zingiber officinale has retained its antibacterial property in both the extraction system. n-hexane extract of ginger at high concentration was found to be most effective in controlling bacterial growth in the form of zone of inhibition, indicating its dose dependent nature.
