Metabolite Identification
Common NameCajanone
DescriptionCajanone belongs to the class of organic compounds known as 3'-prenylated isoflavanones. These are isoflavanones featuring a C5-isoprenoid unit at the 3'-position. Thus, cajanone is considered to be a flavonoid. Cajanone has been detected, but not quantified in, pigeon peas (Cajanus cajan) and pulses. This could make cajanone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Cajanone.
