Infobox references

Fisetinidin is an anthocyanidin. It has been obtained from the heartwood of Acacia mearnsii,^[1] from the bark of Rhizophora apiculata^[2] and can also be synthesized.^[3]

Tannins

Fisetinidin can compose tannins.^[1] The polymers are then called profisetinidin (Porter, 1992).^[2]
