  1. aThe tested samples were compounds 1: euphol 3-O-cinnamate; 8: (E)- 4'-hydroxystilbene-3,5-O-β- diglucopyranoside and chloramphenicol (for bacteria) and nystatin (for C. albicans) used as the reference antibiotics (RA); the crude extract (FPR) and fractions (FPR1 to 5) from F. polita roots;
  2. bThe tested microorganisms were Providencia smartii (P. smartii); Pseudomonas aeruginosa (P. aeruginosa); Klebsiella pneumoniae (K. pneumoniae); Staphylococcus aureus (S. aureus); Salmonella typhi (S. typhi); Escherichia coli (E. coli); Candida albicans (C. albicans). (-): not determined because MIC value was not detected up to 512 μg/ml; (nd): not determined; >512: value above 512 μg/ml.
