Metabolite Identification

Common Name

Homopisatin

Description

Homopisatin, also known as variabilin?, belongs to the class of organic compounds known as pterocarpans. These are benzo-pyrano-furano-benzene compounds, containing the 6H-[1]benzofuro[3,2-c]chromene skeleton. They are derivatives of isoflavonoids. Homopisatin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, homopisatin has been detected, but not quantified in, several different foods, such as herbs and spices, lentils, pulses, and tea. This could make homopisatin a potential biomarker for the consumption of these foods.
