A New Auronolignan from the Cotinus coggygria Heartwood

A new auronolignan, named cotinignan B, was isolated from Cotinus coggygria Scop. Structure elucidation was performed on the basis of 1 H, 13 C NMR, COSY, NOESY, HSQC, and HMBC experiments, supported with HR-ESI-MS, IR and UV. Additional J-HMBC NMR experiment was essential to resolve the configurati...

Zusammenfassung:A new auronolignan, named cotinignan B, was isolated from Cotinus coggygria Scop. Structure elucidation was performed on the basis of 1 H, 13 C NMR, COSY, NOESY, HSQC, and HMBC experiments, supported with HR-ESI-MS, IR and UV. Additional J-HMBC NMR experiment was essential to resolve the configuration of the trisubstituted double bond. This compound represents the secondly discovered natural compound belonging to the rare auronolignan type.
