Characterization of Flavonoids and Naphthopyranones in Methanol Extracts of Paepalanthus chiquitensis Herzog by HPLC-ESI-IT-MSn and Their Mutagenic Activity

A HPLC-ESI-IT-MSn method, based on high-performance liquid chromatography coupled to electrospray negative ionization multistage ion trap mass spectrometry, was developed for rapid identification of 24 flavonoid and naphthopyranone compounds. The methanol extracts of the capitulae and scapes of P. c...
