Propolis is a resinous substance collected by bees (Apis mellifera) from various tree buds which they then use to coat hive parts and to seal cracks and crevices in the hive. Propolis, a known ancient folk medicine, has been extensively used in diet to improve health and to prevent disease. In the present study, we have evaluated the effects of ethanolic extracts of Brazilian propolis group l2 ...

The variations in the chemical composition, and consequently, on the biological activity of the propolis, are associated with its type and geographic origin. Considering this fact, this study evaluated propolis extracts obtained by supercritical extraction (SCO2) and ethanolic extraction (EtOH), in eight samples of different types of propolis (red, green and brown), collected from different reg...

The present study is aimed to evaluate the chemical characterization and antimutagenic potential of propolis extracted in three different solvents (ethanol, polyethylene glycol water). properties extracts were identified using HPLC-DAD LC?MS/MS extract found be richer than ethanolic water considering composition. In addition, activities determined Ames assay. concentrations 3, 1.5 0.75 mg plate...

Background: Candidiasis is one of the most common fungal infections in immunosuppressed patients. The condition is usually treated with local and systemic antifungal agents. Given the antifungal properties of propolis, it appears this natural resin material can be effective in treating this infection. The aim of the present in vitro study was to compare the effect of Iranian propolis with those...

Brazilian green propolis is a resinous substance prepared by bees from parts of the plant Baccharis dracunculifolia. As it possess several biological properties, this work assessed the cytotoxic/anticytotoxic, genotoxic/antigenotoxic and mutagenic/antimutagenic potential of ethanolic extracts of Brazilian green propolis (EEGP) and of B. dracunculifolia (EEBD), by means of the Allium cepa test s...

Background: With considering the importance of natural products for their remedial and therapeutic value, this research was aimed to analyze the chemical compositions and antimicrobial activity of four propolis samples from different areas of Iran (Chenaran, Taleghan, Morad Beyg, and Kalaleh) with various climates and flora. Methods: Ethanolic (70% EtOH) and dichlromethane (DCM) extracts of Ira...

Article history: Received on: 05/05/2016 Revised on: 17/07/2016 Accepted on: 19/10/2016 Available online: 31/01/2017 Antimicrobial resistance (AMR) is among the threats to global public health, with developing countries being mostly affected. The AMR has undermined development of new antimicrobial agents by pharmaceutical industries despite new emerging infections. This necessitates a search fo...

BACKGROUND Propolis and Hypericum perforatum L. are natural products which contain many active compounds and have numerous beneficial effects, including an antitumor effect. Gliobmastoma multiforme (GBM) is a common primary brain tumor with poor prognosis and limited treatment options. In this study, the effect of propolis (EEP) combined with H. perforatum L. (HPE) on glioblastoma cell line U87...
