The Triple Botanical Origin of Russian Propolis from the Perm Region, Its Phenolic Content and Antimicrobial Activity

Russian propolis from the Perm Region was studied by GC-MS, its antibacterial activity was determined, and the bioactive compounds (total phenolics and flavonoids) were quantified by spectrophotometric methods. It was found that Permian propolis belonged to a bee-glue type of triple plant origin: aspen-birch-poplar. Such propolis type has not yet been described. It contains many constituents which could be responsible for diverse biological activities: antibacterial, antifungal, antiviral, antioxidant, anti-inflammatory, and anti-tumor. The combination of the protective excretions of three plant species, resulting in the presence of secondary plant metabolites of many different structural classes gives reason to believe that the pharmacological actions are implemented in different, complementary mechanisms. Together with the detected antibacterial activity, this observation leads to the expectation that such combination could be especially effective in treatment of infections of different origin..
