EXTRA NOTES |
Liquiritin is found in herbs and spices. Liquiritin is isolated from Glycyrrhiza glabra (licorice) and Glycyrrhiza uralensis (Chinese licorice) Liquiritin has been shown toexhibit anti-depressant function (PMID 18289754). Liquiritin belongs to the family of Flavonoid O-Glycosides. These are compounds containing a carbohydrate moiety which is o-glycosidically linked to one of the flavonoid backbones (2-phenylchromen-4-one, 3-phenylchromen-4-one or 4-phenylcoumarin).(HMDB) Other RN: 17654-21-6, 30372-08-8, 31564-20-2, 100483-53-2 |
