Abstract
A new auronolignan, named cotinignan B, was isolated from Cotinus coggygria Scop. Structure elucidation was performed on the basis of 1H, 13C 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. [ABSTRACT FROM AUTHOR]
