Metabolite Identification
Common NameCepharadione A
DescriptionCepharadione A belongs to the class of organic compounds known as aporphines. These are quinoline alkaloids containing the dibenzo[de,g]quinoline ring system or a dehydrogenated derivative thereof. Cepharadione A is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, cepharadione a has been detected, but not quantified in, herbs and spices. This could make cepharadione a a potential biomarker for the consumption of these foods.
