ANTIMICROBIAL ACTIVITY OF THE PLANT EXTRACTS

Bacterial pathogens	Zone of Inhibition (mm)*
	H. indicus (1 mg/ml)	F. bengalensis (1 mg/ml)	P. marsupium roxb (1 mg/ml)
Staphylococcus aureus	14±0.01	12±0.02	13±0.01
Pseudomonas aeruginosa	12±0.02	10±0.01	11±0.02
Klebsiella pneumoniae	14±0.01	13±0.01	12±0.01

^*Values are mean±SD (n=3). Aqueous extract from the roots of H. indicus and from the bark of F. bengalensis and P. marsupium roxb was used for the assessment of antibacterial activity against selected bacterial pathogens.
