General description

Alternariol belongs to the dibenzo-pyrones chemical group. It is a mycotoxin present in indoor air, soil and plants.

Application

Alternariol from Alternaria sp. may be used as a calibration standard in reverse phase high-performance liquid chromatography (HPLC) and UV-spectrum analysis. It may also be used to spike wholemeal wheat flour for wet baking studies

Biochem/physiol Actions

Alternaria mycotoxins are generally associated with undried food grains post-harvest. The disease caused by Alternaria mycotoxin results in a discolored halo in fruits and spotting in leaves. Alternariol (AOH) is cytotoxic and fetotoxic to microbes and mammalian cells. AOH displays inhibitory effect on cell proliferation and has estrogenic functionality.

The stability of the Alternaria mycotoxins alternariol, alternariol monomethyl ether, and altenuene upon bread baking was investigated by model experiments using a spiked wholemeal wheat flour matrix. For alternariol and alternariol monomethyl ether, but not for altenuene, degradation products, formed
