Publication date: December 2018Source: Biochemical Systematics and Ecology, Volume 81Author(s): Luisa Possamai Gimenes, Juliano Geraldo Amaral, Marcelo Monge, João Semir, João Luis Callegari Lopes, Norberto Peporine Lopes, Anelize BauermeisterAbstractThe genus Eremanthus has been studied in the last decades from the taxonomic, phytochemistry and ecological perspectives, although the chemical composition of several of its species are still poorly known. In this work, some high polar chemical constituents of E. incanus was identified using a high-performance liquid chromatography analytical technique combined with sequential mass spectrometry (HPLC-ESI-MSn). The phytochemical investigation allowed the identification of 20 compounds in E. incanus, including different analogs of flavonoids, chlorogenic acids and glycosylated phenolic derivatives. All of these compounds are being described for the first time in E. incanus. The chemotaxonomic significance of chlorogenic acids, flavonoids and, especially, glycosylated phenolic derivatives in E. incanus has been summarized. This chemical profile was compared with another species of the genus Eremanthus (E. capitatus) and also with a species of another genus (Minasia alpestris) from Vernonieae subtribe.
