Antimicrobial activity of extracts and isoquinoline alkaloids of selected papaveraceae plants

Popis výsledku v původním jazyce

Alkaloidal extracts of seven selected plants of the family Papaveraceae were studied with respect to their activity against six strains of pathogenic bacteria and their alkaloidal fingerprint. Twenty-four alkaloids were determined by GC/MS, and twenty ofthem identified from their mass spectra, retention times and retention indexes. In the antibacterial assay, three Gram-positive (Enterorococcus faecalis, Staphylococcus aureus and S. hyicus), and three Gram-negative (Escherichia coli, Proteus mirabilisand Pseudomonas aeruginosa) strains were used. The most promising antimicrobial activity was shown by the alkaloidal extract of Macleaya cordata with MIC values of 16 ?g/mL for Staphylococcus aureus, 32 ?g/mL for Enterococcus faecalis and 64 ?g/mL for Staphylococcus hyicus and Escherichia coli. All the tested pure isoquinoline alkaloids were considered inactive within the tested concentrations.
