| dc.description.abstract | Propolis is a natural product with a complex chemical composition, which varies largely by geographical area and plant species visited by bees. Although the propolis collected from the same geographical area has similarities in chemical composition, specific compounds are also attested, due to the local flora. Over the years, numerous studies have been carried out on the chemical composition of propolis, but for the moment there is no common procedure for obtaining and analyzing propolis extracts, which makes it difficult to use the product in the food, cosmetics and pharmaceutical industries. In the present study we aimed to analyze the chemical composition of propolis extracts obtained by maceration with the use of 60%, 70% and 80% ethyl alcohol as solvent, in order to identify the main compounds and analyze the influence of solvent concentration on the extraction of active ingredients. For this purpose, GC-MS and UV-Vis analysis were performed, which confirmed that the predominant constituents are flavanoids with unsubstituted B ring, a characteristic aspect of propolis originating from the temperate zone. | en |
