The present study mainly focuses on the potential antibacterial value of ethanol leaf extract of Andrographis paniculata against pathogenic bacteria
Escherichia coli, Klebsiella peneumoniae, Proteus vulgaris and Streptococcus pneumoniae by disc diffusion method. Bioactive compound andrographolide
was isolated from the leaf. The results revealed that the ethanol leaf extract and andrographolide compound are potent in inhibiting these bacteria and
this work highlights that the inhibitory effect is on par with standard antibiotics.
