Chemical Information
FooDB NameAesculetin
DescriptionAesculetin, also known as cichorigenin or cichoriin aglucon, belongs to the class of organic compounds known as 6,7-dihydroxycoumarins. These are coumarins bearing two hydroxyl groups at positions 6 and 7 of the coumarin skeleton, respectively. Aesculetin is an extremely weak basic (essentially neutral) compound (based on its pKa). Aesculetin is found, on average, in the highest concentration within sherries. Aesculetin has also been detected, but not quantified in, several different foods, such as beers, tarragons, peanuts, highbush blueberries, and barley. This could make aesculetin a potential biomarker for the consumption of these foods.

anti pyretic35493 A drug that prevents or reduces fever by lowering the body temperature from a raised state. An antipyretic will not affect the normal body temperature if one does not have fever. Antipyretics cause the hypothalamus to override an interleukin-induced increase in temperature. The body will then work to lower the temperature and the result is a reduction in fever.DUKE
