“…Propolis is a natural product collected by honeybees from various plant sources growing around hives, including flowers, buds, or tree exudates [ 1 , 2 , 3 ]. Extracts of propolis have been used in folk medicine since early times for numerous purposes, especially as a remedy for various diseases [ 4 , 5 , 6 ].…”

“…Extracts of propolis have been used in folk medicine since early times for numerous purposes, especially as a remedy for various diseases [ 4 , 5 , 6 ]. Currently, propolis is being extensively investigated in various applications, especially in medicine, pharmacy, cosmetology, and the food industry [ 1 , 3 ]. It is used as a component of functional food, dietary supplements, preparations for cold symptoms, or dermatological preparations used in wound healing [ 6 , 7 ].…”

“…According to the literature data, the biological activity of propolis is mainly attributed to the presence of phenolic compounds, especially flavonoids, phenolic acids, and their esters [ 1 , 6 , 10 ]. For this reason, the phenolic fraction is the most extensively investigated among all constituents determined in propolis samples collected from various geographical regions [ 3 , 9 , 12 , 14 ]. Phenolic compounds regularly determined in poplar-type propolis samples include pinocembrin, galangin, chrysin, kaempferol, catechin, quercetin, rutin, pinostrobin, pinobanksin, naringenin, caffeic acid, coumaric acid, ferulic acid, caffeic acid phenethyl ester, or caffeic acid cinnamyl ester [ 11 , 14 , 15 , 16 , 17 , 18 ].…”

Effect of the Solvent on Propolis Phenolic Profile and its Antifungal, Antioxidant, and In Vitro Cytoprotective Activity in Human Erythrocytes Under Oxidative Stress

Propolis is a natural bee product with various beneficial biological effects. The health-promoting properties of propolis depend on its chemical composition, particularly the presence of phenolic compounds. The aim of this study was to evaluate the relationship between extraction solvent (acetone 100%, ethanol 70% and 96%) and the antifungal, antioxidant, and cytoprotective activity of the extracts obtained from propolis. Concentrations of flavonoids and phenolic acids in the propolis extracts were determined using ultrahigh-performance liquid chromatography. The antioxidant potential of different extracts was assessed on the basis of 2,2-diphenyl-1-picrylhydrazyl (DPPH·) free-radical-scavenging activity, Fe3+-reducing power, and ferrous ion (Fe2+)-chelating activity assays. The ability of the extracts to protect human red blood cell membranes against free-radical-induced damage and their antifungal activity was also determined. The results showed that the concentration of flavonoids in the propolis extracts was dependent on the solvent used in the extraction process and pinocembrin, chrysin, galangin, and coumaric acid were the most abundant phenols. All extracts exhibited high antioxidant potential and significantly protected human erythrocytes against oxidative damage. On the other hand, the antifungal activity of the propolis extracts depended on the solvent used in extraction and the fungal strains tested. It needs to be stressed that, to the best of our knowledge, there is no study relating the effect of solvent used for extraction of Polish propolis to its phenolic profile, and its antifungal, antioxidant, and cytoprotective activity.

“…Probit analyses were used to calculate 24 h and 48 h LD 50 values. Measures of uncertainty were estimated with SE, and measure differences were indicated with 95% confidence intervals (Finney 1952). A Schneider-Orelli (1947) adjustment for background mortality was applied.…”

“…Honey bee colonies collect plant resins, creating propolis (Burdock 1998;Bankova et al 2019) that they use to seal and strengthen the nest. Propolis also has antibacterial, antifungal and antiviral activity (Freitas et al 2019) and is potentially produced in response to colony infections, to maintain colony health, or both (Simone-Finstrom and Spivak 2012; Gherman et al 2014;Erler and Moritz 2016). Propolis may also help to suppress Nosema infection (Gherman et al 2012;Yemor 2016), and other natural products may also help.…”

Highlights Ethanol and DMSO induced underlying effects on propolis' antibacterial activity. Sonication enhanced propolis activity in an aqueous formulation. The duration of sonication significantly influenced the antibacterial activity of the propolis dispersions. Propolis dispersions provoked cell injury at low sonication times and cell death at high sonication times. Propolis dispersions caused membrane fractions resulting in cell swelling possibly due to water absorption.
