Propolis is a complex mixture composed by salivary secretions of bees and a resinous and balsamic material collected by them from different part of plants. This material is well employed by people due its antimicrobial, antioxidant, anti-inflammatory, antiviral properties beside others. However, the chemical composition varies according the habitat and season. This work describes the identification of saturated hydrocarbons, methyl cinnamate, sitosterol cinnamate and ananixanthone isolated from the brown propolis produced in Bahia, Brazil, classified as Propolis Type 6. Besides, antioxidant activities and cytotoxicity of the extracts were evaluated by the DPPH quenching and Brine Shrimp Test. The extracts showed weak antioxidant activities and high cytotoxicity, especially the methanol and chloroformic extracts.
