Abstract. Ipomoea carnea is a species found in Brazil, and is considered toxic to animals. The study aimed to assess the phytochemical composition and biological activities of the floral extract of I. carnea. Flowers were collected and the hydroethanolic extract produced. Phytochemistry was evaluated for numerous groups of secondary metabolisms, biological activities were performed to reduce the free radical DPPH, toxicity on Artemia salina and photoprotective action. Phytochemical prospecting demonstrated the presence of several classes of phytocomposites of great importance for industries, antioxidant activity with IC50 = 13.26 µL mL-1, lethality concentration on A. salina with LC50 = 455.31µg mL-1 and ultraviolet protection factor UVA, UVB and UVC. The hydroethanolic floral extract showed potential with several phytochemical classes and biological activities.
