Chemical Information
FooDB NameOryzalexin E
DescriptionOryzalexin E belongs to the class of organic compounds known as hydrophenanthrenes. These are a phenanthrene derivative where at least one ring CC bond is substituted by hydrogenation. Oryzalexin E has been detected, but not quantified in, rice (Oryza sativa). This could make oryzalexin e a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Oryzalexin E.
