The major components were mono- and diglycosides of flavonoids and naphthopyranones. Eleven compounds, including four new flavonol glycosides, were identified based on their fragmentation patterns in MS experiments and on NMR analysis of the isolated compounds. The described data may contribute to a better understanding of the taxonomic classification of the Eriocaulaceae family.1651-1656engLC/MS/MSEriocaulon ligulatumflavonoidsnaphthopyranonesArtigoWOS:000272754100011Acesso restrito35382536406029770000-0003-3032-2556
