“…In the mid-latitudes of the northern hemisphere, the plant precursor of propolis is the bud resins (exudates) of some arboreous trees, in particular, different species of poplar, aspen, and birch (Bankova et al 2000;Wilson et al 2013Wilson et al , 2015Isidorov et al 2014aIsidorov et al , 2016. The antimicrobial activity of this natural antibiotic has been attributed to phenolic substances: flavonoid aglycones, and phenolic and hydroxycinnamic acids (Kujumgiev et al 1999).…”

“…Recent publications have demonstrated that the principal plant precursors of propolis from boreal and temperate zones of the European continent are the bud resins of black poplar (Populus nigra ), downy birch (Betula pubescens ), and common aspen (Populus tremula ) (Isidorov et al 2014a). In a more recent investigation, taxonomical markers of the resins from the buds of these trees were determined (Isidorov et al 2016).…”

“…Black poplar bud resin is characterized by a high content of phenols such as pentenyl (mostly, prenyl) cinnamates, chalcones, and the unsubstituted B ring flavonoids: pinocembrin, pinostrobin, chrysin, galangin, pinobanksin, and their 3-substituted derivatives (Isidorov and Vinogorova 2003). Downy birch and common aspen bud resins are disting u i s h e d b y t h e p r e s e n c e o f s p e c i f i c phenylpropenoids, hydroxycinnamic acid esters of sesquiterpene alcohols, and glycerol, respectively (Isidorov et al 2014a(Isidorov et al , 2016. Although bees from the same colony often collect resins from more than one of these tree species, three main Btypes^of European propolis can be distinguished on the basis of the species-specific chemical composition: poplar-, birch-, and aspen-type (Popova et al 2012;Isidorov et al 2014aIsidorov et al , 2016.…”

-Typical European propolis is an antibiotic substance derived from the resin of poplar, birch, and aspen buds. Here, we tested the ability of propolis originating from the resins of these plants to inhibit the in vitro growth of Paenibacillus larvae , the organism that causes American foulbrood, a fatal honeybee larval disease. The study involved GC-MS analysis of extracts from nine samples of propolis gathered from the temperate climate zone of Europe. The extracts showed noticeable differences in the content of flavonoids and other phenolic compounds. Despite the differences in chemical composition, all tested extracts inhibited the growth of P. larvae , with a minimum inhibitory concentration of 7.8 to 62.4 μg mL −1. It was found that not only did the content of flavonoids affect the strength of antimicrobial activity, but other phenolics, such as the phenylpropenoids hydroxycinnamyl sesquiterpenols, glycerides and benzoates also had an effect. This is the first report on the comparative activity of different types of European propolis against P. larvae.Paenibacillus larvae / American foulbrood / Apis mellifera / propolis / antibacterial action

This review updates the information upon the chemical composition of propolis from all Mediterranean countries as well as their biological properties and applications. The non‐volatile fraction of propolis was characterized by the presence of phenolic acids and their esters and flavonoids. Nevertheless, in some countries, diterpenes were also present: Sicily (Italy), Croatia, Malta, Creta (Greece), Turkey, Cyprus, Egypt, Libya, Algeria and Morocco. The volatile fraction of propolis was characterized by the presence of benzoic acid and its esters, mono‐ and sesquiterpenes, being the oxygenated sesquiterpene β‐eudesmol characteristic of poplar propolis, whereas the hydrocarbon monoterpene α‐pinene has been related with the presence of conifers. Regardless the chemical composition, there are common biological properties attributed to propolis. Owing to these attributes, propolis has been target of study for applications in diverse areas, such as food, medicine and livestock.

Propolis is a complex natural product that possesses antioxidant, anti‐inflammatory, immunomodulatory, antibacterial, and antiviral properties mainly attributed to the high content in flavonoids, phenolic acids, and their derivatives. The chemical composition of propolis is multifarious, as it depends on the botanical sources from which honeybees collect resins and exudates. Nevertheless, despite this variability propolis may have a general pharmacological value, and this review systematically compiles, for the first time, the existing preclinical and clinical evidence of propolis activities as an antiviral and immunomodulatory agent, focusing on the possible application in respiratory diseases. In vitro and in vivo assays have demonstrated propolis broad‐spectrum effects on viral infectivity and replication, as well as the modulatory actions on cytokine production and immune cell activation as part of both innate and adaptive immune responses. Clinical trials confirmed propolis undeniable potential as an effective therapeutic agent; however, the lack of rigorous randomized clinical trials in the context of respiratory diseases is tangible. Since propolis is available as a dietary supplement, possible use for the prevention of respiratory diseases and their deleterious inflammatory drawbacks on the respiratory tract in humans is considered and discussed. This review opens up new perspectives on the clinical investigation of neglected propolis biological properties which, now more than ever, are particularly relevant with respect to the recent outbreaks of pandemic respiratory infections.
