N2 - A purple pigment neocandenatone (vestitol[6→9″;7O→7″] obtusaquinone) was isolated from the heartwood of campincerán (Dalbergia congestiflora), an endemic Mexican tree. The isoflavan-cinnamyl phenol quinone methide structure of this compound was elucidated by HRMS, IR, and 1H and 13C NMR spectroscopic analysis, including 2D experiments (COSY, NOESY, HMQC and HSQC).
