Alternariol (abbreviation: AOH ) and its monomethyl ether (abbreviation: AME) are mycotoxins are formed by fungi of the genus Alternaria, in particular Alternaria alternata. Their biosynthesis is via a polyketide pathway. Because of the ubiquitous distribution of Alternaria spp. come their toxins found in many foods. They are found in vegetables and fruits such as tomatoes, potatoes, tangerines, melons, grapes, apples, raspberries or strawberries, in cereals such as millet, wheat, or rye, olive or nuts. During the acute toxicity of AOH and AME is low, they show in vitro a significant mutagenic activity. They are associated with the development of esophageal cancer.
