Metabolite Identification
Common NameCyclobrassinin
DescriptionCyclobrassinin belongs to the class of organic compounds known as 3-alkylindoles. 3-alkylindoles are compounds containing an indole moiety that carries an alkyl chain at the 3-position. Cyclobrassinin has been detected, but not quantified in, several different foods, such as brassicas, cauliflowers (Brassica oleracea var. botrytis), chinese cabbages (Brassica rapa), chinese mustards (Brassica juncea), and swedes (Brassica napus). This could make cyclobrassinin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Cyclobrassinin.
