Abstract A new prenylated flavanone, floranol ( 1 ) 3,5,7,2′‐ tetrahydroxy‐6‐methoxy‐8‐prenylflavanone and a known flavanone (dioclein) were isolated from the roots of Dioclea grandiflora (Fabaceae). The structure and the relative stereochemistry were established by 2D NMR spectroscopic techniques (HMQC and HMBC) Copyright © 2002 John Wiley & Sons, Ltd.
