title: Alkaloids from Corydalis marschalliana.
abstract: The known alkaloids (+/-)-stylopine, (+/-)-sinactine, protopine, (+)-bulbocapnine, (-)-domesticine, (+)-corydine and (+)-isoboldine were found in the mixture of alkaloids from Corydalis marschalliana (Papaveraceae), growing in Bulgaria. The alkaloids dehydronantenine, (+)-nantenine and oxonantenine were isolated for the first time from this plant. The spectral data of these alkaloids are given. In addition, three unidentified alkaloids (Cm-4, Cm-11 and Cm-12), in a small quantities, were described.
