Flavanones

Naringenin is a flavanone from the flavonoid group of polyphenols. It is commonly found in citrus fruits, especially as the predominant flavonone in grapefruit.

Eriodictyol is a bitter-masking flavanone, a flavonoid extracted from yerba santa (Eriodictyon californicum), a plant native to North America. Eriodictyol is one of the four flavanones identified in this plant as having taste-modifying properties, the other three being homoeriodictyol, its sodium salt, and sterubin.

Pinocembrin is a flavanone, a type of flavonoid. It is an antioxidant found in damiana, honey, fingerroot, and propolis.

chemical compound

8-Prenylnaringenin (8-PN; also known as flavaprenin, '(S)-8-dimethylallylnaringenin, hopein, or sophoraflavanone B') is a prenylflavonoid phytoestrogen. It is reported to be the most estrogenic phytoestrogen known. The compound is equipotent at the two forms of estrogen receptors, ERα and ERβ, and it acts as a full agonist of ERα. Its effects are similar to those of estradiol, but it is considerably less potent in comparison.

Poriol is a C-methylated flavanone, a type of flavonoid. It is found in Pseudotsuga menziesii (Douglas fir) in reaction to infection by Poria weirii.

chemical compound

Alpinetin is a phytochemical isolated from a variety of plants including those of the genus Alpinia. It is going through tests to see if it is a vasorelaxant.

Liquiritigenin is a flavanone that was isolated from Glycyrrhiza uralensis, and is found in a variety of plants of the Glycyrrhiza genus, including Glycyrrhiza glabra (licorice). It is an estrogenic compound which acts as a selective agonist of the ERβ subtype of the estrogen receptor (ER), though it is also reported to act as an ERα partial agonist at sufficient concentrations. It also has a choleretic effect.
