Metabolite Identification
Common NameIsoplumbagin
DescriptionIsoplumbagin 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). Isoplumbagin has been detected, but not quantified in, nuts. This could make isoplumbagin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Isoplumbagin.
