[Alkaloids and flavonoid from aerial parts of Hammada articulata ssp. scoparia].
Two alkaloids (N-methylisosalsoline and carnegine) had been previously described from the aerial parts of Hammada articulata ssp. scoparia. A thorough study of this plant material has now led to the isolation of eight minor alkaloids and one flavonoid. The alkaloids include four isoquinolines (isosalsoline, salsolidine, dehydrosalsolidine and isosalsolidine), one isoquinolone (N-methylcorydaldine), tryptamine, N-omega-methyltryptamine and one beta-carboline (tetrahydroharman). The flavonoid has been identified as isorhamnetin-3-O-beta-D-robinobioside. The structures have been elucidated on the basis of spectral data, mainly mass spectrometry (D-IC) and 1H NMR.
