Metabolite Identification
Common NameIsoliquiritin
DescriptionIsoliquiritin belongs to the class of organic compounds known as flavonoid o-glycosides. Flavonoid O-glycosides are compounds containing a carbohydrate moiety which is O-glycosidically linked to the 2-phenylchromen-4-one flavonoid backbone. Isoliquiritin has been detected, but not quantified in, several different foods, such as red tea, green tea, teas (Camellia sinensis), fruits, and black tea. This could make isoliquiritin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Isoliquiritin.
