Since the beginning of propolis research, several groups have studied its antibacterial, antifungal, and antiviral properties. However, most of these studies have only employed propolis ethanolic extract (PEE) leading to little knowledge about the biological activities of propolis water extract (PWE). Based on this, in a previous study, we demonstrated the anti-inflammatory and immunomodulatory...

The bees of the Meliponini tribe, known as stingless (SB), elaborate a distinct type propolis, whose application potential is largely unexplored. Currently, there some knowledge pharmacological activities propolis from Apis mellifera, however, little about diversity and antimicrobial activity especially in relation to pathogens agricultural importance. This study aimed investigate alcoholic ext...

Silylated ethanolic extract of two propolis samples from Kazan and Marmaris regions in Turkey were investigated by capillary GC-MS. The compounds were characterized by comparison with library searches. Twenty four compounds from Kazan samples were identified, eight of them were new for propolis. Eighteen compounds from Marmaris samples were identified, two of them were new for propolis.

the effect of ethanolic extract of iranian green propolis, rosemary and earthworm meal to determine on performance, immune system and blood metabolites of japanese quail, using 160 mixed-sex quail chicks in a completely randomized design by four treatments (including ethanolic extract of propolis 0.1 percent, rosemary leaves meal 0.5 percent, earthworm meal 0.5 percent and control) and four rep...

BACKGROUND In the present study, we examined the antioxidant effect of water soluble derivative of propolis (WSDP) and ethanolic (EEP) extract of propolis on renal and liver function in alloxan-induced diabetic mice. In addition, we examined whether different extract of propolis could prevent diabetic nephropathy and liver toxicity by inhibiting lipid peroxidation in vivo. METHODS Diabetes wa...

new approaches for treatment of infectious diseases in aquatic animals have important roles in aquaculture technology progress. in the present study, in vitro effects of different extracts of propolis, royal jelly and pollen obtained from beehives have been investigated on aquatic pathogenic bacterial isolates. the isolated bacteria identified on the basis of their biochemical properties and se...

BACKGROUND Antibiotic resistance is an emerging public health problem. Centers for Disease Control and Prevention (CDC) has described antibiotic resistance as one of the world's most pressing health problems in 21st century. WHO rated antibiotic resistance as "one of the three greatest threats to human health". One important strategy employed to overcome this resistance is the use of combinatio...

We investigated the effects of the two fractions, aqueous (AEP) and ethanolic extracts of propolis (EEP) of the Brazilian propolis on azoxymethane (AOM)-induced aberrant crypt foci (ACF). Male Wistar Hannover (GALAS) rats were administered two weekly subcutaneous injections of AOM (20 mg/kg bw) and fed with diets mixed with AEP (100, 500 and 1,000 ppm) or EEP (500 and 1,000 ppm) for 4 weeks, st...

In the current study, ultrasonic assisted ethanolic extract of propolis was discussed in detail, including their total phenolic content, antioxidant capacity and radical scavenging capacity. For this purpose, we determined by CUPRAC FRAP) assay. At same time, free extracts investigated via DPPH• CUPRAC- hydroxyl (HRS) methods. The chemical constituents were characterized ATR-FTIR. results revea...

Recently, two chemically different types of Brazilian propolis (type-3 and -12) were shown to have cariostatic properties. This study aimed to evaluate the influence of their isolated fractions on mutans streptococci viability, glucosyltransferases (GTFs) activity and caries development in rats. The ethanolic extracts of propolis (EEPs) were serially fractionated into hexane (H-fr), chloroform,...
