Majoranin

5,6-Dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7,8-dimethoxy-4H-1-benzopyran-4-one

C18H16O8 (360.0845136)


Majoranin, also known as 5,6,4-trihydroxy-7,8,3-trimethoxyflavone or mucroflavone b, is a member of the class of compounds known as 8-o-methylated flavonoids. 8-o-methylated flavonoids are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, majoranin is considered to be a flavonoid lipid molecule. Majoranin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Majoranin can be found in a number of food items such as peppermint, herbs and spices, mentha (mint), and fats and oils, which makes majoranin a potential biomarker for the consumption of these food products. Majoranin is found in common thyme. Majoranin is isolated from Majorana hortensis (sweet majoram), and Thymus vulgaris (thyme).
