Common Name

5,7-Dihydroxy-3',4',5'-trimethoxyflavone

Description

5,7-Dihydroxy-3',4',5'-trimethoxyflavone, also known as tricetin 3',4',5'-trimethyl ether, belongs to the class of organic compounds known as 4'-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C4' atom of the flavonoid backbone. Thus, 5,7-dihydroxy-3',4',5'-trimethoxyflavone is considered to be a flavonoid. 5,7-Dihydroxy-3',4',5'-trimethoxyflavone has been detected, but not quantified in, a few different foods, such as barleys (Hordeum vulgare), breakfast cereal, and cereals and cereal products. This could make 5,7-dihydroxy-3',4',5'-trimethoxyflavone a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on 5,7-Dihydroxy-3',4',5'-trimethoxyflavone.
