Catunaregin ( 1 ) and epicatunaregin ( 2 ), two novel norneolignans with a unique O‐bridged furopyran ring, together with three known neolignans, ficusal, balanophonin, and 5″‐methoxy‐4″‐ O ‐(8‐guaiacylglycerol)buddlenol A, were isolated from the stem bark of Catunaregam spinosa , a Chinese mangrove associate. Their structures were elucidated by spectroscopic means, including two‐dimensional NMR techniques. Compounds 1 and 2 exhibited moderate inhibition against the mammary cancer F10 cell line.
