Identification of glycosil flavones and determination in vitro of antioxidant and photoprotective activities of Alternanthera brasiliana L. Kuntze

Abstract

The study Alternanthera brasiliana (L.) Kuntze aims to prove its effectiveness in folk medicine. From the study of their chemical constitution were identified by LC-MS technique three glycosylated flavones than were called 2"-O-ramnosylvitexin; 4',5,7-trimethoxy-2"-Oramnosylvitexin and Ligustroflavone. The tests showed high antioxidant capacity of the specie and in small concentrations showed too high levels of photoprotection. In addition its high capacity for photoprotection also paves its use in cosmetology. Alternanthera brasiliana is a species extremely promising with all parameters to become a herbal medicine. © 2014 Academic Journals Inc.
