Chemistry:Vioxanthin
From HandWiki
Vioxanthin is a mycotoxin that was first isolated from the pathogenic fungus Trichophyton violaceum and characterized in 1966.[1] It is a pigment with a brownish-yellow color.[1] It has since been found to be a constituent of a variety of other fungi including those in the genus Penicillium[2] and Aspergillus.[3] The detection of vioxanthin in food products has been used as evidence of contamination with these fungi.[4]
A laboratory synthesis of vioxanthin has been reported.[5]
