Natural Product Identification

Common Name

3,4-dihydroxy-7-methoxy-2,2,6-trimethyl-3h,4h-pyrano[3,2-c]quinolin-5-one

Description

Zanthodioline belongs to the class of organic compounds known as pyranoquinolines. These are polycyclic compounds containing a pyran ring fused to a quinoline moiety. Quinoline or benzo[b]pyridine is a bicyclic compound that consists of benzene fused to a pyridine. Zanthodioline is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Zanthodioline has been detected, but not quantified in, fruits and herbs and spices. 3,4-dihydroxy-7-methoxy-2,2,6-trimethyl-3h,4h-pyrano[3,2-c]quinolin-5-one is found in Zanthoxylum beecheyanum and Zanthoxylum simulans. This could make zanthodioline a potential biomarker for the consumption of these foods.
