ANTIMICROBIAL AND ANTIOXIDANT ACTIVITY OF Andrographis echioides (L.) Nees LEAVES EXTRACTS Authors: K. Jeevanantham And A. Zahir Hussain*
ABSTRACT
The objectives of this study were to determine antimicrobial and antioxidant activities of
methanolic leaves extracts of Andrographis echioides (L.) Nees. Antimicrobial activity was
examined against four gram positive, four gram negative bacterial and two fungal strains. The
methanolic leaves extracts was subjected to assess their antioxidant potential using various in
vitro methods such as DPPH, ABTS, FRAP and reducing power assay. The methanolic leaves
extract of Andrographis echioides (L.) Nees was more effective antioxidant activity compared to
standard. Methanolic leaves extracts of Andrographis echioides (L.) Nees found to be potentially
effective against Gram positive (Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus)
gram negative (Pseudomonas aeruginosa, E. coli, Klebsiella pneumonia) bacteria and fungi
(Aspergillus niger, Candida albicans). The present study concludes the medicinal significance of
Andrographis echioides (L.) Nees extracts having potential antimicrobial and antioxidant
properties which leads to pharmaceutical applications.
