The species of the subfamily Barnadesioideae (Asteraceae) comprise a monophyletic group with ca. 91 species entirely restricted to South America. Phylogenetic studies based on morphology and DNA demonstrate the importance of this subfamily in understanding the evolutionary relationships of the Asteraceae family. In addition, several species of this subfamily are included in traditional medicine systems, especially in Andean countries, where they are used for their anti-inflammatory, antimicrobial and antitussive properties, among many others. Although the species of the subfamily Barnadesioideae present a broad commercialization in marketplaces and medicinal plant markets, so far there are few reports of analytical methodologies for the authentication and quality control of plant material and marketed phytomedicines. Considering the advent of the metabolomics as a modern approach applied to the analysis of plant matrices and medicinal plants, this project aims to explore the chemotaxonomy, authentication and quality control of the species of the subfamily Barnadesioideae (Asteraceae) via metabolomic studies using hyphenated techniques (UHPLC-UV-MS) and chemometrics.
