Resumo

Researches involving antioxidant compounds from natural sources are in evidence recently, especially because of its importance in preventing the formation of free radicals. This application can be important to develop topical products for antiaging effects or for internal use focusing in the prevention of deleterious effects of the free radical species in the organism. Propolis is a complex mixture produced by bees from the plant exsudates, consisting of resinous and balsamic material. The chemical composition includes flavonoids, terpenoids and phenylpropanoids and many others (ROCHA et al. 2011). Antibacterial, antiviral and antioxidant activities have usually been attributed to flavonoids and phenolic compounds (Bergonzini & Volpi, 2006). However, nowadays, many different extraction processes exists (alcoholic and aqueous) and the pharmaceutical technology are improving the extracts options to work in different pharmaceutical applications, like the glycolic and dry extracts. Then, the characterization of chemical and antioxidant properties of these new options of propolis extracts can be valuable to the pharmacists that work with new products.
