It is a metabolite of the pea phytoalexin (+)-pisatin, produced by the pea-pathogenic Fusarium oxysporum forma specialis pisi, and a number of other fungi, including Fusarium anruioides, Fusarium avenaceum, Mycosphaerella pinodes, and Stemphylium botryosum. It is a member of pterocarpans and a tertiary alcohol. It is functionally related to a (+)-maackiain."}]
