Ionic liquids (IL) are innovative alternative solvents to recover bioactive compounds from plant-based sources to replace toxic volatile organic solvents (VOS). ILs are tailored-made solvents with chemical and thermal stabilities, nonvolatile and noninflammable. Although ILs are versatile, cost-effective, and sustainable solutions, the European Commission (EC) has no current regulation to approve extracts obtained with ILs to be applied in foods.

The dataset showed in this manuscript belongs to the investigation of the Southern-Brazilian geopropolis of stingless bees. Stingless bees are native species of insects from tropical areas; they produce honey, pollen and geopropolis that is composed of a mix of vegetal extracts, digestive enzymes, and mostly by soil. Used in folk medicine as antiseptic, antioxidant and antimicrobial agent, the composition is due to bee species, climate changes, local flora, and soil type.

Geopropolis is a stingless bee product compose mainly by soil, presenting complex composition geopropolis has bioactive compounds that will depend on geographical characteristics as well bee species, changing their chemical and biological properties. Thus the study aims to evaluate the solubility and chemical stability of geopropolis extracts, through radical capture capacity and reducing capacity. Besides, analysis of free and bonded phenolic compounds, and mineral composition.

Background: Vancomycin is an antibiotic of growing importance in the treatment of hospital infections, with particular emphasis on its value in the fight against methicillin-resistant Staphylococcus aureus. However its usage profile must be evaluated to assure maximum benefit and minimum risk.

Findings: A cross-sectional retrospective study was carried out among inpatients that received vancomycin in a Brazilian quaternary hospital.

Article Synopsis
  • Bacterial infections from drug-resistant strains are a major health issue and a leading cause of death, highlighting the need for new antibacterial agents.
  • Four snake venoms were tested against 10 resistant bacterial strains to explore their antibacterial potential.
  • The study found that the venoms of A. rhodostoma, B. atrox, and B. jararaca show promise as effective sources for developing new antibiotics, with potential for further pharmacological exploration.
