Chemical Information

FooDB Name

Thymoquinone

Description

Thymoquinone, also known as TQ, belongs to the class of organic compounds known as p-benzoquinones. These are benzoquinones where the two C=O groups are attached at the 1- and 4-positions, respectively. Thymoquinone is found, on average, in the highest concentration within winter savories (Satureja montana). Thymoquinone has also been detected, but not quantified in, herbs and spices. This could make thymoquinone a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Thymoquinone.
