Description | 3,3',5-Trihydroxy-4',7-dimethoxyflavanone, also known as taxifolin 7,4'-dimethyl ether, belongs to the class of organic compounds known as 7-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. 3,3',5-Trihydroxy-4',7-dimethoxyflavanone is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 3,3',5-Trihydroxy-4',7-dimethoxyflavanone has been detected, but not quantified in, tea. Blumeatin B is found in Blumea balsamifera, Blumea fistulosa, Eupatorium capillifolium, Ageratina altissima and Iris potaninii. This could make 3,3',5-trihydroxy-4',7-dimethoxyflavanone a potential biomarker for the consumption of these foods. |
