  • Abstract

    Spices are the key ingredients of the Indian food. Inspite of enhacing flavour of food, these are found to have medicinal importance too which is shown in our study. In this study, the antibacterial activity of aqueous leaf extracts of Mentha arvensis (Mint), Curcuma longa (Turmeric), Piper nigrum (Black pepper), Zingiber officinale (ginger) and Azadirachta indica (Neem) was evaluated against Escherichia coli and Bacillus subtilis by agar well diffusion method. The maximum antimicrobial activity expressed in terms of zone of inhibition was shown by aqueous extract of Zingiber officinale followed by Curcuma longa and Azadirachta indica. However, aqueous extract of Piper nigrum was only effective against B. subtilis and Mentha arvnesis did not show any activity against both the test organisms. This study scientifically validates the use of plants as a potent antibacterial agent.
