CHEMICAL STUDIES ON THE MINOR ISOQUINOLINE ALKALOIDS FROM CORYDALIS-SOLIDA SUBSP BRACHYLOBA
Continuing our studies on Corydalis species growing in Turkey, from which isoquinoline alkaloids have been isolated, we have investigated another species, Corydalis solida subsp. brachyloba (Papaveraceae, Fumarioideae). As a result (+)-fumarophycine (1), (-)-corpaine (2), (-)-ophiocarpine (3), 13-methyl-columbamine (4), (1)-corydalidzine (5), (+)-fumarit ine (6), (-)-africanine (7) and (-)-corybrachylobine (8) have been obtained along with other isoquinoline alkaloids (+)-fumariline (+), parfumine, (+/-)-sibiricine, (-)-canadine, (-)-sinactine, (-)-corydalmine, (+)-scoulerine, berberine, dehydrocorydaline, oxocularine, oxosarcocapnidine, (+)-bicuculline, (+)-alpha-hydrastine, (+)-bulbocapnine, (+)-isoboldine, norsanguinarine, (+)-chelidimerine, protopine, beta-allocryptopine, (-)-norjusiphine and corydaldine. The minor alkaloid, (-)-corybrachylobine was characterized as a new isoquinoline alkaloid.
