Use of mass spectrometry as a tool for the search or identification of flavonoids in Urticaceae

Abstract The Urticaceae family, circumscribed within the Rosales, was investigated in this study with an overview of current literature about phytochemical studies using Liquid Chromatography coupled to Mass Spectrometry (LC-MS) technique. aim review secondary metabolites identified Urticaeae LC-MS analysis. A systematic performed Scifinder and ScienceDirect databases. Phenolic substances are most abundant especially flavones, phenolic acids, flavonols. We have shown that flavonoids important chemotaxonomic markers chemical composition Urticaeae. Following attributes, C-glycosylated O-glycosylated flavones stand out as main skeletons. Our results revealed profile structural variability micromolecules from each genus Urticaceae. This approach demonstrates a greater use reversed-phase liquid chromatography mass spectrometer negative mode electrospray ionization (ESI) source. In addition, mobile phase is usually composed binary systems eluted by gradient systems. Finally, paper presents identification molecular ion patterns fragmentation Urticaceae, isolated LC-MS, which has been proven be valuable tool several areas, such phytochemistry, chemosystematics, chemophenetics. conclusion, expected help identify separate compounds family.
