Chemical Information
FooDB NameJuglone
DescriptionJuglone, also known as antibiotic PD7 or ci 75500, belongs to the class of organic compounds known as naphthoquinones. Naphthoquinones are compounds containing a naphthohydroquinone moiety, which consists of a benzene ring linearly fused to a bezene-1,4-dione (quinone). Juglone is an extremely weak basic (essentially neutral) compound (based on its pKa). Juglone is found, on average, in the highest concentration within a few different foods, such as black walnuts, common walnuts, and liquors. Juglone has also been detected, but not quantified in, butternuts and nuts. This could make juglone a potential biomarker for the consumption of these foods.
