flavonoid

 or flavone

Organic compound, any member of a class of biological pigments containing no nitrogen that are found in many plants. They include anthoxanthins, which give yellow colours, often to flower petals, and anthocyanins, largely responsible for the red colouring of buds and young shoots and the purple and purple-red colours of autumn leaves. Their biological function is unknown; they may attract pollinators and seed dispersers.
