Pratol
Pratol is a flavonoid, 4′-''O''-methylated 4′,7-dihydroxyflavone. It can be found in ''Trifolium pratense ''Trifolium pratense'', the red clover, is a herbaceous species of flowering plant in the bean family Fabaceae, native to Europe, Western Asia, and northwest Africa, but planted and naturalized in many other regions.

4',7-Dihydroxyflavone
4′,7-Dihydroxyflavone is a flavone. It is found in ''Medicago truncatula'' in relation with the root nodulation symbiont ''Sinorhizobium meliloti'' or in seeds of '' Sophora viciifolia''. Like many other flavonoids, 4′,7-dihydroxyflavone has been found to possess activity at opioid receptors ''in vitro''. Specifically, it acts as an antagonist of the μ-opioid receptor and, with lower affinity, of the κ- and δ-opioid receptor The δ-opioid receptor, also known as delta opioid receptor or simply delta receptor, abbreviated DOR or DOP, is an inhibitory 7-transmembrane G-protein coupled receptor coupled to the G protein Gi/G0 and has enkephalins as its endogenous lig ...s.

Flavonoid
Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6. According to the IUPAC nomenclature, they can be classified into: *flavonoids or bioflavonoids *isoflavonoids, derived from 3-phenyl chromen-4-one (3-phenyl-1,4-benzopyrone) structure *neoflavonoids, derived from 4-phenylcoumarine (4-phenyl-1,2-benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins ( flavones and flavonols). This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavonoid have also been more loosely used to describe non ...

Trifolium Pratense
''Trifolium pratense'', the red clover, is a herbaceous species of flowering plant in the bean family Fabaceae, native to Europe, Western Asia, and northwest Africa, but planted and naturalized in many other regions. Description Red clover is a herbaceous, short-lived perennial plant, variable in size, growing to tall. It has a deep taproot which makes it tolerant to drought and gives it a good soil structuring effect. The leaves are alternate, trifoliate (with three leaflets), each leaflet long and broad, green with a characteristic pale crescent in the outer half of the leaf; the petiole is long, with two basal stipules that are abruptly narrowed to a bristle-like point. The flowers are dark pink with a paler base, long, produced in a dense inflorescence, and are mostly visited by bumblebees. Distribution The red clover is native to Europe, Western Asia, and northwest Africa, but it has been naturalized in other continents, like North and South America. Specificall ...
