Term Name: biflavonoid
Synonyms: biflavonoids, diflavonoid, diflavonoids
Definition: A flavonoid oligomer that is obtained by the oxidative coupling of at least two units of aryl-substituted benzopyran rings or its substituted derivatives, resulting in the two ring systems being joined together by a single atom or bond.
