Alternariol is a toxic metabolite of Alternaria fungi.[1] It is an important contaminant in cereals and fruits.[2] Alternariol exhibits antifungal and phytotoxic activity. It is reported to inhibit cholinesterase enzymes.[3] It is also a mycoestrogen.

A 2017 in vitro assay study reported alternariol to be a full androgen agonist.[4]
