“…The temperatures of 5 and 50% mass loss were also lower for propolis PW (160 and 305 °C cf. 165 and 325 °C for propolis PM, respectively); this indicated that the higher content of volatile essential oil present in propolis PW occurred together with water, ash, crude EtOH extract, and an insoluble part . At 65 °C, the maximum peak of crystal‐phase melting was observed for both the PM and PW bee glue.…”

“…, propolis is composed of resin (50–55%), plant wax sand beeswax (30–40%), essential oils (5–10%), peptides (bee pollen), microelements (Cu, Si, Mg, Mn, Zn), and vitamins from B, E, H, and P groups. Polish propolis contains water, essential oils, ash, crude EtOH extract, and an insoluble part . Ethanol extract, obtained via the dissolution of propolis in 70% EtOH (1:10) for 5 days at room temperature and evaporation of EtOH to a content of 65% of the crude mass, contained about 5% flavonoid compounds (flavones, flavanoles, flavanones, and chalkones), mainly chrysin, galangin, pinocembrin and pinobanksin, aliphatic (mainly propionic and 3,4‐dihydroxybutyric) and aromatic acids, ethyl or phenyl ethyl esters of cinnamon, caffeic, izoferulic, benzoic, or salicylic acid, terpenes, sesquiterpenes, steroids, bioelements, and enzymes.…”

“…Polish propolis consists mainly of phenolic compounds, acrylic and aromatic compounds, phenols, phenolic acids, and caffeic acid esters . According to the newest research data, propolis needs to be treated as a plant product, being a wax secretion of leaf gemmas of some trees or a substance produced by plants after their damage . Bees add to it a wax and a small amount of their gland secretion.…”

The numerous applications of polymers in many areas of our lives make it necessary to protect them from aging. Increases in the safety and time of polymer material exploitation demands the application of antidegradants with broad scopes of action. In this study, crude propolis, originating from two geographical regions of Poland, was used to protect peroxide‐cured natural‐rubber vulcanizates filled with silica or carbon black from degradation by oxygen, ozone, and microorganisms. Thermogravimetry analysis confirmed the stability of propolis under the curing conditions. From vulcametric torque measurements and determinations of the mechanical properties, we determined that the incorporation of propolis did not adversely affect the performance of the natural‐rubber vulcanizates. The addition of propolis to the rubber mix made the vulcanizates resistant to thermooxidative and ozone aging and protected them from biodegradation in soil and the action of microorganisms. © 2017 Wiley Periodicals, Inc.

“…Among different types of honey, a strong antibacterial effect was observed in manuka honey which contains larger amount of methylglyoxal than European honeys [50]. The antibiotic activity of manuka honey is estimated by Unique Manuka Factor (UMF) and methylglyoxal (MGO) markers [46]. Due to an increased content of glucose oxidase, a higher level of hydrogen peroxide than in European honeys can be observed [51].…”

Honey, propolis, bee pollen, bee bread, royal jelly, beeswax and bee venom are natural products which have been used in medicine since ancient times. Nowadays, studies indicate that natural bee products can be used for skin treatment and care. Biological properties of these products are related to flavonoids they contain like: chrysin, apigenin, kaempferol, quercetin, galangin, pinocembrin or naringenin. Several pharmacological activities of phenolic acids and flavonoids, and also 10-hydroxy-trans-2-decenoic acid, which is present in royal jelly, have been reported. Royal jelly has multitude of pharmacological activities: antibiotic, antiinflammatory, antiallergenic, tonic and antiaging. Honey, propolis and pollen are used to heal burn wounds, and they possess numerous functional properties such as: antibacterial, anti-inflammatory, antioxidant, disinfectant, antifungal and antiviral. Beeswax is used for production of cosmetics and ointments in pharmacy. Due to a large number of biological activities, bee products could be considered as important ingredients in medicines and cosmetics applied to skin.

A novel honey-based product enriched with coumarin from Melilotus flowers

et al. 2019

Coumarin is a plant secondary metabolite responsible for the health-promoting properties of the Melilotus officinalis herb used in traditional medicine in the treatment of lymphedema and chronic venous diseases. The aim of this study was to analyze the possibility of honey enrichment with coumarin derived from sweet clover (Melilotus) in two different ways: herb honey and herb-infused honey production. Herb honey was obtained by feeding bees with sugar syrup enriched with a M. officinalis herb water infusion, whereas herbal macerates in multifloral honey were prepared with crushed flowers (fresh and dried) of M. officinalis and Melilotus albus at 20 °C in dark place for 6 months. Melilotus albus nectar honey (n = 14) was used as control. Using HPLC analysis, the highest content of coumarin (from 41.33 to 137.89 mg/kg) and its precursor o-coumaric acid (from 6.57 to 25.15 mg/kg) in M. officinalis flowers-infused honey were found. Herb honey contains 4.48 mg/kg coumarin and for the first time, this compound was determined in nectar honey from Polish M. albus honey (0.05 to 0.88 mg/kg). The addition of Melilotus flowers enhanced antioxidant activity (measured by FRAP, DPPH and PCL methods) of infused-honey in comparison to multifloral honey (control) and herb honey. The coumarin and o-coumaric acid were weakly correlated with antioxidant activity. It was found that only herb-infused honey can be proposed as the natural safe remedy for venous diseases prevention.
