Chemical profile of Eriocaulon ligulatum (Vell.) L.B. Smith (Eriocaulaceae)

Two new and six known flavonoids and two known naphthopyranones have been isolated by chromatographic methods and spectrometrically identified in capitulae and scapes of Eriocaulon ligulatum (Vell.) L.B. Smith (Eriocaulaceae). The presence of naphthopyranones suggests approximation between Eriocaulon and Paepalanthus genus.
