INVITRO ANTIBACTERIAL ACTIVITY OF TERMINALIA CHEBULA RETZ. AND CISSUS QUADRANGULARIS L. ON FOOD POISONING BACTERIAC. JESPIN IDAAbstract The purpose of this study was to evaluate the efficacy of various extracts of stem of Cissus quadrangularis and fruits of Terminalia chebula against some food poisoning bacteria such as Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa and Escherichia coli. The antibacterial activity of different solvent extracts (ethyl acetate and methanol) of these plants was determined by using disc diffusion method. Results revealed that ethyl acetate extract of C.quadrangularis exhibited significant antibacterial activity against all the tested bacteria except P. aeruginosa. The methanolic extract of T. chebula showed maximum zone of inhibition against the bacteria B. cereus. From the present study it is clear that these two plants may have the potential to be used as natural medicine against food poisoning bacteria. However there is a need for further research to isolate the bio-active compounds responsible for antibacterial activity.
