The conversion of curcumin by soybean lipoxygenase leads to three stereoisomers of 2‐[(4′‐hydroxy‐3′‐methoxy)phenoxy]‐4‐(4″‐hydroxy‐3″‐methoxy‐(phenyl)‐8‐hydroxy‐6‐oxo‐3‐oxabicyclo[3.3.0]‐7‐octene. Their structures and conformational behaviour were elucidated by various 1 H and 13 C NMR methods and high‐performance liquid chromatography–electrospray ionization tandem mass spectrometry.
