Pollenitin is found in tea. 3,4',5,8-Tetrahydroxy-7-methoxyflavone 3,5,8-Trihydroxy-2-(4-hydroxyphenyl)-7-methoxy-4H-1-benzopyran-4-one 4',5,8-Trihydroxy-7-methoxyflavonol 7-O-Methylherbacetin Pollenitin C16H12O7 316.2623 316.058302738 3,5,8-trihydroxy-2-(4-hydroxyphenyl)-7-methoxy-4H-chromen-4-one pollenitin 24487-56-7 COC1=C(O)C2=C(C(O)=C1)C(=O)C(O)=C(O2)C1=CC=C(O)C=C1 InChI=1S/C16H12O7/c1-22-10-6-9(18)11-13(20)14(21)15(23-16(11)12(10)19)7-2-4-8(17)5-3-7/h2-6,17-19,21H,1H3 VRODWQGSCHPDJK-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.
