Abstract Cristacarpin, a new phytoalexin fromErythrinacrista-galli is assigned the structure (−)-3,6a-dihydroxy-9-methoxy-10-γ,γ-dimethylallyl- cis -pterocarpan. It is accompanied by the known phytoalexins phaseollidin and demethylmedicarpin in this plant. Cristacarpin, phaseollidin and demethylmedicarpin were also obtained from E. sandwicensis and (together with isomedicarpin) from the related legume
