Exhibits antioxidant properties. Tamarixetin is found in fats and oils. 3,3',5,7-Tetrahydroxy-4'-methoxyflavone 3,5,7-Trihydroxy-2-(3-hydroxy-4-methoxyphenyl)-4H-1-benzopyran-4-one 3',5,7-Trihydroxy-4'-methoxyflavonol 4'-O-Methylquercetin Quercetin 4'-methyl ether Tamarixetin C16H12O7 316.2623 316.058302738 3,5,7-trihydroxy-2-(3-hydroxy-4-methoxyphenyl)-4H-chromen-4-one tamarixetin 603-61-2 COC1=C(O)C=C(C=C1)C1=C(O)C(=O)C2=C(O)C=C(O)C=C2O1 InChI=1S/C16H12O7/c1-22-11-3-2-7(4-9(11)18)16-15(21)14(20)13-10(19)5-8(17)6-12(13)23-16/h2-6,17-19,21H,1H3 FPLMIPQZHHQWHN-UHFFFAOYSA-N belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position.
