Article Synopsis
  • Plant extracts, particularly from hops, show strong antimicrobial activity against Staphylococcus aureus strains, effective in both free-floating and biofilm forms, making them viable for oral care.
  • The hop extract worked as well as standard antibiotics (amikacin, ciprofloxacin, and ceftriaxone) and exhibited synergy, enhancing the effectiveness of these antibiotics against various bacterial isolates.
  • Chemical analysis of the extract identified key compounds (prenylated flavonoids and acylphloroglucides) that contribute to its antimicrobial effects and ability to reduce the minimum inhibitory concentration (MIC) of antibiotics, suggesting its potential as both an antiseptic and a complement to conventional treatments.

Recent advances in investigations of chemical structure of lignin give rise to questions about relationship between chemical structure and topology of the macromolecules. In this paper, we made a comparison of results of the studies of chemical and topological structures of lignins. The features of topological structure of lignins of birch and apple wood were identified on the basis of the study of dilute solutions of the lignins by the sedimentation-diffusion analysis and viscometry.
