Metabolite Identification
Common NameRishitin
DescriptionRishitin belongs to the class of organic compounds known as 1,2-diols. These are polyols containing an alcohol group at two adjacent positions. Rishitin has been detected, but not quantified in, several different foods, such as red bell peppers (Capsicum annuum), alcoholic beverages, garden tomatoes (Solanum lycopersicum), green bell peppers (Capsicum annuum), and garden tomato (var.). This could make rishitin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Rishitin.
