Talauma ovata St. Hil. (Magnoliaceae) is a big tree, which the trunk bark has been used in folk medicine against fever. Chemical analysis of nine populations showed the occurrence of two chemotypes in well-defined geographic localization. The first chemotype is characterized by neolignans and is found in latitude bellow 20°S. The second chemotype contains sesquiterpenes, mainly the sesquiterpene lactone costunolido, and can be found above latitude 21°S.
