Nonylphenol (NP) has been considered an endocrine disrupting substance causing reproductive dysfunction and increase in reactive oxygen species production in different organs including testis. Propolis is a honeybee product that has an antioxidant property. The aim of this study was to elucidate the protective effects of propolis against reproductive toxicity induced by NP in male rats. Five ex...
Propolis is a natural product derived from plant resins collected by honeybees. It is used by bees as glue, a general-purpose sealer, and as draught-extruder for beehives. Propolis has been used in folk medicine for centuries. It is known that propolis possesses anti-microbial, antioxidative, anti-ulcer and anti-tumor activities. Therefore, propolis has attracted much attention in recent years ...
Propolis is a complex honeybee product with resinous aspect, containing plant exudates and beeswax. Their color, texture, and chemical composition vary, depending on the location of the hives and local flora. The most studied Brazilian propolis is the green (alecrim-do-campo) type, which contains mainly prenylated phenylpropanoids and caffeoylquinic acids. Other types of propolis are produced i...
BACKGROUND Some toothpastes, cosmetics and ointments contain propolis, a bee product, and it is increasingly popular as a dietary supplement. Although propolis is known to cause contact allergy, there have been no studies of the prevalence of this. OBJECTIVES This study aimed to determine the prevalence of contact allergy to propolis in beekeepers and any relationship between propolis allergy...
Although propolis is one of the most popular functional foods for human health, there have been no comprehensive studies of herb-drug interactions through cytochrome P450 (CYP) inhibition. The purpose of this study was to determine the inhibitory effects of propolis on the activities of CYP1A2, 2A6, 2B6, 2C9, 2C19, 2D6, 2E1 and 3A4 using pooled human liver microsomes (HLMs). Propolis inhibited ...
Tlak Gajger I., Pavlović I., Bojić M., Kosalec I., Srečec S., Vlainić T., Vlainić J. (2017): Components responsible for antimicrobial activity of propolis from continental and Mediterranean regions in Croatian. Czech J. Food Sci., 35: 376–385. Propolis is a popular subject of research worldwide due to its therapeutic potential. The antimicrobial activity of propolis appears to be promising but ...
Objective: This research is aimed to determine antibacterial activity of some solvents of raw propolis extracts of Trigona sp from Sulawesi, Indonesia and compare it with antibacterial activities of ethanolic and aqueous extracts. Methods: Propolis samples were extracted with water, ethanol, propylene glycol, olive oil, and Virgin Coconut Oil (VCO). An agar-well diffusion assay was used to eval...
Propolis, a honeybee product, has gained popularity as a food and alternative medicine. Its constituents have been shown to exert pharmacological (anticancer, antimicrobial and anti-inflammatory) effects. We investigated whether Brazilian green propolis exerts neuroprotective effects in the retina in vitro and/or in vivo. In vitro, retinal damage was induced by 24 h hydrogen peroxide (H2O2) exp...
Stingless bees collect plant resins and make it into propolis, although they have a wider range of use for this material than do honey bees (Apis spp.). Plebeia spp. workers employ propolis mixed with wax (cerumen) for constructing and sealing nest structures, while they use viscous (sticky) propolis for defense by applying it onto their enemies. Isolated viscous propolis deposits are permanent...
Propolis is a gum-like product which are gathered by bees from various plants, and which vary in color from light yellow to dark brown. It is known that the propolis have antibacterial, anticarcinogenic, and immunostimulating biological activities. Parts of these activities are probable due to the antioxidative effect of some compounds which occur in relatively higher concentrations in propolis...
