Natural Product Identification

Common Name

3,3,5-trimethyl-11h-pyrano[3,2-a]carbazol-8-ol

Description

Koenine belongs to the class of organic compounds known as carbazoles. Carbazoles are compounds containing a three ring system containing a pyrrole ring fused on either side to a benzene ring. Koenine is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Koenine has been detected, but not quantified in, herbs and spices. 3,3,5-trimethyl-11h-pyrano[3,2-a]carbazol-8-ol is found in Murraya koenigii and Murraya kwangsiensis. This could make koenine a potential biomarker for the consumption of these foods.
