CONCLUSION
On the basis of experimental result, it was concluded that are extract which are obtain from different Indian spices -
Cuminum cyminum, Elettaria cardamomum, Corianderum sativum Piper nigrum and Cinnamomum verum show
inhibitory effect on the Vibrio species which cause gastrointestinal diseases. Antimicrobial studies were investigated
using agar well diffusion method to determine the effect of these spices against the Vibrio species. Black pepper
(Piper nigrum) showed maximun antibacterial activity zone on 100% ethanol and methanol extract and minimum at
70% ethanol extract of spices. Coriander (Coriandrum sativum) showed maximun antibacterial activity zone on 85%
ethanol extract and minimum at 70% ethanol extract. Cinnamon (Cinnamomum verum) showed maximun
antibacterial activity zone was observed on 85% as well as 100% acetone extract and minimum at 70% ethanol.
Green Cardamom (Elettaria cardamomum) also showed a very significant effect against Vibrio species. Maximun
inhibitory zone on 100% ethanol and minimum at 70% methanol as well as acetone. Thus these spices possess
potential bioactive compounds which could be further isolated and identified by advanced analytical techniques.
And these compounds can be used to curb the growth of bacterial species including vibrio.
