Genkwanin

Description

Genkwanin, also known as 7-methylapigenin, belongs to the class of organic compounds known as 7-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, genkwanin is considered to be a flavonoid. Genkwanin is a bitter tasting compound. Genkwanin has been detected, but not quantified in, several different foods, such as common sages (Salvia officinalis), common thymes (Thymus vulgaris), rosemaries (Rosmarinus officinalis), sweet basils (Ocimum basilicum), and winter savories (Satureja montana). This could make genkwanin a potential biomarker for the consumption of these foods. Genkwanin 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 significant number of articles have been published on Genkwanin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Genkwanin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Genkwanin is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
