Flavonoids
Flavonoids can be subdivided into many different classes including flavones, flavonols, flavonones, isoflavones and flavonol-3-ols and anthocyanidins. Regardless of the individual subdivisions, all contain the benzo-γ-pyrone architecture and are classified according to the presence of different substituents on the rings and to the degree of saturation of the benzo-γ-pyrone ring. Within the flavone class, the most active mast cell stabilizers are luteolin, disometin and apigenin
