The bioguided fractionation methodology was successful in detecting antimicrobial metabolites against Staphylococcus aureus strains and permitted the description of undescribed guaianolide-type sesquiterpene lactones with substitution patterns matching all those described in the Oxylobinae subtribe.engAsteraceaeKaunia lasiophthalmaantimicrobial activitybioguided studyguaianolidesArtículo Científico Publicado
