new tetrahydroprotoberberine alkaloid from Corydalis caseana A. gray

The isolation and structure of a new tetrahydroprotoberberine alkaloid from C. caseana is reported. This alkaloid, named caseanadine, has a phenolic hydroxyl at C-1 and methoxyls at C-2, -9, and -10. Its structure has been deduced from an analysis of its p.m.r. mass, and i.r. spectra. The alkaloid h...

Zusammenfassung:	The isolation and structure of a new tetrahydroprotoberberine alkaloid from C. caseana is reported. This alkaloid, named caseanadine, has a phenolic hydroxyl at C-1 and methoxyls at C-2, -9, and -10. Its structure has been deduced from an analysis of its p.m.r. mass, and i.r. spectra. The alkaloid has a substitution pattern different from other members of this group of alkaloids of established structure.
