propolis has traditionally been used in curing infections and healing wounds and burns. current researches have shown that propolis has antibacterial, antifungal and antiviral actions however, the pharmacological activity of propolis is highly variable depending on its geographic origin. there have been few studies on the effects of iranian propolis on the oral microorganisms. in this in-vitro ...

Propolis is known for its biological properties and its preparations have been continuously investigated in an attempt to solve the problem of their standardization, an issue that limits the use of propolis in food and pharmaceutical industries. The aim of this study was to evaluate in vitro antioxidant, antimicrobial, antiparasitic, and cytotoxic effects of extracts of red, green, and brown pr...

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 was extracted using water and various concentrations of ethanel as solvents. The extracts vvere inyestigated by measurement o £ absorption spectr-m with a UV spectrophotometer, reversed phase-high pressure thin-layer chromatography and reyersed phase-HPLC, Maximum absorption ef all extracts was 290 iim, resembling fiavo"oid compounds, and the 80% ethanolic extract showed highest absorp...

Removing the bacteria, including Enterococcus faecalis, from the root canal is one of the important aims in endodontic treatment.We aimed to compare the antibacterial activity of Chlorhexidine with two natural drugs. The antibacterial activities of three different propolis extracts (alcohol concentrations: 0, 15, 40%) and Aloe vera gel on E. faecalis were compared using three methods: disk dif...

Ethanolic and aqueous extracts of the "bee glue" Propolis exhibit antioxidative properties and are used as antiinflammatory drugs in folk medicine. In order to standardize the principle activities of prominent components of these extracts, simple biochemical tests have been introduced in the preceding paper. These activity tests prove the high antioxidative and inhibitory capacities of aqueous ...

BACKGROUND Propolis is the bee product noted for multiple biological effects, and therefore it is widely used for the prevention and treatment of a variety of diseases. The active substances of propolis are easily soluble in ethanol. However ethanolic extracts cannot be used in treatment of certain diseases encountered in ophthalmology, pediatrics, etc. Unfortunately, the main biologically acti...

Ethanolic extracts of Propolis are used as antiinflammatory and wound healing drugs since ancient times. In order to facilitate a comparison of different extracts, the standardization on the basis of quantitative determination of prominent components of these extracts has been substituted for simple biochemical "activity" tests. One of these activity tests bases on the inhibition of peroxidase-...
