Anthocyanidins (aglycones) and anthocyanins (glycosides) are common plant pigments and belong to a structural subclass of flavonoids characterized by a 2-phenylbenzopyrylium unit. They are derived along the flavonoid modification pathways and further separated into three types, pelargonidin, cyanidin, and delphinidin, due to the different number of hydroxyl groups in the phenyl group.
