Summary:In this study, the phytochemical profile of extracts from the flowers of Bromelia laciniosa was characterized. The total phenolic and flavonoids contents were determined and the antioxidant and photoprotective activities were evaluated using in vitro assays. Phytochemical analysis demonstrated that the extracts were found to be positive for the presence of anthracene derivatives, anthraquinones, coumarins, flavonoids and tannins, lignans, mono and diterpenes. The ethanol extract (Bl-EtOH) presented the most significant total phenolic content (53.75 ± 1.25 mg GAE/g). The dichloromethane extract (Bl-CH 2 Cl 2 ) showed the highest flavonoid content (46.06 ± 1.18 mg CE/g). The methanol extract (Bl-MeOH) was the most effective extract in the DPPH (2,2-diphenyl-1-picrylhydrazil) assay (EC 50 141.90 ± 3.01 μg/mL). Bl-EtOH and Bl-MeOH showed higher sun protection factor at a concentration of 100 mg/L (3.38 ± 0.04 and 3.78 ± 0.11, respectively). Therefore, the extracts proved to be interesting for the development of new studies aiming their incorporation into photoprotective cosmetic formulations.
