Neocandenatone, an isoflavan-cinnamylphenol quinone methide pigment from Dalbergia congestiflora.
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).
