Three flavone glycosides, including the novel 6-hydroxyluteolin 7-O-gentiobioside, and a bitter secoiridoid glycoside, swertiamarin, were identified in the aerial parts of L. carinthiacum. Four minor xanthone glycosides were also detected. Separations were made with droplet counter-current chromatography (DCCC) in combination with column chromatography. Structure elucidation was achieved by UV, 1H and 13C NMR, FDMS [field desorption mass spectrometry] and D/CIMS [desorption/chemical ionization mass spectrometry] spectra.
