Metabolite Identification
Common NameCajaisoflavone
DescriptionCajaisoflavone belongs to the class of organic compounds known as 6-prenylated isoflavanones. These are isoflavanones featuring a C5-isoprenoid unit at the 6-position. Thus, cajaisoflavone is considered to be a flavonoid. Cajaisoflavone has been detected, but not quantified in, pigeon peas (Cajanus cajan) and pulses. This could make cajaisoflavone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Cajaisoflavone.
