Metabolite Identification
Common NameLepidine D
DescriptionLepidine D belongs to the class of organic compounds known as diphenylethers. These are aromatic compounds containing two benzene rings linked to each other through an ether group. Lepidine D has been detected, but not quantified in, brassicas and garden cresses (Lepidium sativum). This could make lepidine D a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Lepidine D.
