In the present article, we examined the antimicrobial, antifungal and antimalarial activities of two crude extracts 1, 4 (ethanol and methanol) and two fractions 2, 3 (dichloromethane and ethyl acetate) what isolated from Polygonum hydropiper. Antimicrobial activity was tested against Candida albicans, Escherichia coli, Pseudomonas aeruginosa, Cryptococcus neoformans, Aspergillus fumigatus, Klebsiella pneumonia and methicillin resistant Staphylococcus aureus (MRSa). Samples 1 and 3 were effective against A. fumigates. Sample 1 was mild active against K. pneumoniae with IC50 of 9.0 μg/mL. Sample 2 demonstrated mild activity against E. coli and C. neoformans with IC50 of 10.0 and 13.0 μg/mL, respectively.
