Background/Objectives: This study aimed to develop gel nanoemulsions (NEs) of Brazilian essential oils (EOs) from Eugenia uniflora and Psidium guajava, as well perform chemical characterization investigate the antimicrobial activity EOs NEs. Results/Conclusions: The main compounds E. EO were curzerene (34.80%) germacrene B (11.92%), while those P. guajava β-caryophyllene (25.92%), β-selinene (22.64%), γ-selinene (19.13%). NEs had droplet sizes 105.30 99.50 nm polydispersity index (PDI)...
The aim of this study was to evaluate the physicochemical composition and antibacterial activity Brazilian propolis extracts from different types, concentrations, extraction solvents regions in Brazil. A total 21 samples were analyzed, comprising 14 Apis mellifera (12 green, 1 brown, red) 7 stingless bees (3 mandaçaia, 2 jataí, hebora, tubuna). analyses performed dry extract, phenolic content (TPC) antioxidant (DPPH ABTS). by Determination Minimal Inhibitory Concentration (MIC) Bactericidal...
The aim of this study was to evaluate the antibacterial activity nanoemulsions Baccharis dracunculifolia essential oil. volatile compounds oil were identified using gas chromatography-mass spectrometry. properties (droplet size, polydispersity index, pH, and electrical conductivity) determined. activities its evaluated MIC, MBC, disk diffusion. microorganisms used were: Gram-positive bacteria (Staphylococcus aureus ATCC 25923, Bacillus cereus 14579, Streptococcus mutans 25175, Enterococcus...
