Purpose: In the present study, six flavonoids (5,7-dimethoxyflavanone-4'-O-beta-D-glucopyranoside, 5,7-dimethoxyflavanone- 4'-O-[2 ''-O-(5'''-O-trans-cinnamoyl)-beta-D-apiofuranosyl]-beta-D-glucopyranoside, naringenin-7-O-beta-D-glucopyranoside, 5,7,3'-trihydroxy-flavanone-4'-O-beta-D-glucopyranoside, rutin, and nicotiflorin) isolated from Galium fissurense, Viscum album ssp. album and Cirsium hypoleucum were screened against extended-spectrum beta-lactamase producing multidrug-resistant (trimetoprime-sulphametoxazole, sulbactam-ampicillin, clavulonate-amoxicilin, ceftriaxon, cefepime, imipenem, ceftazidime, tobramicin, gentamicin, ofloxacin, ciprofloxacin) bacteria Klebsiella pneumoniae (ES beta Ls).
