Campomanesia adamantium (Cambess.) O. Berg, Myrtaceae, is a native species. The extracts of ethyl acetate and hexane showed little variation in their chemical composition at different seasons of the year associated with the development of the plant, while the ethanol extract showed significant change in relationship to chemical composition. All ethanol extracts showed high antioxidant activity against DPPH method and from moderate to high antioxidant activity for β-carotene/linoleic acid.
