摘要：

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