Antioxidant Activity of Apis Mellifera Bee Propolis: A Review

Abstract

BackgroundPropolis is a natural product manufactured by bees from balsamic materials collected from plants that surround the hive, undergoing subsequent modification by the enzymes of these insects. It has several functions in the hive, such as sealing cracks and antimicrobial action. Folk medicine worldwide has used this resin in their health practices, and modern research turns its eyes to natural materials to become sources of new molecules to treat the most diverse ailments. AimsThis work collected information on studies that test the antioxidant activity of propolis, produced by Apis mellifera bees, using different antioxidant methods available. MethodsThe search for this review was carried out in the following databases: SciELO, Google Scholar, PubMed, MEDLINE, Catalog of Dissertations and Theses of CAPES, BVS, CRD, Embase, Science Direct, Scopus and Cochrane Library. Publications in Portuguese, English and Spanish in the last decade were included.ResultsThe 173 articles chosen showed quantitative and qualitative data about the potential of this natural product in the area of interest. Propolis extracts reached amazing values in antioxidant tests; they were as active as isolated substances already recognized as standard patterns. Many studies have brought information about the antioxidant mechanisms of propolis, such as free radical scavenging, metal chelation, and electron donation.ConclusionThis review brings scientific evidence, in vitro and in vivo, that supports the idea that propolis is a good candidate for producing new antioxidant pharmaceutical and food formulations in the future
