Campomanesia sessiliflora O. Berg is a medicinal plant that is object of very few studies in the literature. In this context, the antioxidant activity, sun protection factor (SPF) and toxicity in Artemiasalina Leachs were analysed, as well as the contents of phenolic compounds, flavonoids and tannins in aqueous extracts prepared by infusion and maceration of C. sessiliflora leaves. Maceration showed higher levels of phenolic compounds and flavonoids regarding infusion and the two samples had the same tannin content. The LD50 was similar for the extracts, both were considered as low toxicity in the test with A. salina. Infusion presented a SPF of 9.98, while maceration presented a SPF of 6.74. Maceration presented better contents of secondary metabolites and antioxidant activity and infusion presented a better SPF. The extracts have the potential of incorporation into multifunctional products.

Keywords : Secondary metabolites; Artemia salina; Phenolic Compounds.
