Metabolite Identification
Common NamePseudobaptigenin
DescriptionPseudobaptigenin, also known as psi-baptigenin, belongs to the class of organic compounds known as isoflavones. These are polycyclic compounds containing a 2-isoflavene skeleton which bears a ketone group at the C4 carbon atom. Thus, pseudobaptigenin is considered to be a flavonoid. Pseudobaptigenin has been detected, but not quantified in, several different foods, such as common cabbages (Brassica oleracea), mugworts (Artemisia vulgaris), cowpeas (Vigna unguiculata), arctic blackberries (Rubus arcticus), and green bell peppers (Capsicum annuum). This could make pseudobaptigenin a potential biomarker for the consumption of these foods. Pseudobaptigenin is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a small amount of articles have been published on Pseudobaptigenin.
