Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, rhamnazin is considered to be a flavonoid lipid molecule. Rhamnazin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Rhamnazin can be synthesized from quercetin. Rhamnazin can also be synthesized into viscumneoside VII and viscumneoside IV. Rhamnazin can be found in lemon balm, which makes rhamnazin a potential biomarker for the consumption of this food product. Rhamnazin is an O-methylated flavonol, a type of chemical compound. It can be found in Rhamnus petiolaris, a buckthorn plant endemic to Sri Lanka .3,5-Dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-4H-1-benzopyran-4-one, 9CI4',5-Dihydroxy-3',7-dimethoxyflavonolQuercetin 3',7-dimethyl etherRhamnazinC17H14O7330.2889330.0739528023,5-dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy-4H-chromen-4-onerhamnazin552-54-5COC1=CC(O)=C2C(=O)C(O)=C(OC2=C1)C1=CC(OC)=C(O)C=C1InChI=1S/C17H14O7/c1-22-9-6-11(19)14-13(7-9)24-17(16(21)15(14)20)8-3-4-10(18)12(5-8)23-2/h3-7,18-19,21H,1-2H3MYMGKIQXYXSRIJ-UHFFFAOYSA-N belongs to the class of organic compounds known as flavonols.
