Description | Majoranin, also known as mucroflavone b or thymonin, belongs to the class of organic compounds known as 8-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, majoranin is considered to be a flavonoid. Majoranin has been detected, but not quantified in, sweet marjorams (Origanum majorana). This could make majoranin a potential biomarker for the consumption of these foods. Majoranin is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a small amount of articles have been published on Majoranin. |
