Abstract
Heliosupine, heliosupine N-oxide, 3'-acetylheliosupine, and viridiflor ine were isolated and identified on the base of MS, H-1 and C-13 NMR f rom Cynoglossum officinale. Altogether 14 pyrrolizidine alkaloids were separated and identified by GLC and GLC-MS in the alkaloid extracts f rom different parts of Cynoglossum officinale. From Cynoglossum amabil e five pyrrolizidine alkaloids were recorded: supinine, amabiline, rin derine, echinatine, and 3'-O-acetylechinatine. Copyright (C) 1996.
