Metabolite Identification

Common Name

Cajanol

Description

Cajanol belongs to the class of organic compounds known as 7-o-methylated isoflavonoids. These are isoflavonoids with methoxy groups attached to the C7 atom of the isoflavonoid backbone. Isoflavonoids are natural products derived from 3-phenylchromen-4-one. Thus, cajanol is considered to be a flavonoid. Cajanol has been detected, but not quantified in, pigeon peas (Cajanus cajan) and pulses. This could make cajanol a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Cajanol.
