Proanthocyanidins and anthocyanidins are chemical compounds that give many plants, especially fruit or flowers, their red, blue, or purple colors. Even before anthocyanins were recognized as anti-cancer and health-promoting agents, they were studied extensively for their importance as plant pigments. While anthocyanins are responsible for the reds, blues, and purples, the closely related flavonols and flavones (other cancer-preventing pigments) are responsible for the yellow and ivory colors seen in many flowers.
Anthocyanidins belong to a group of compounds called polyphenols, which in turn belong to a subclass called flavonoids.
Food sources of anthocyanidins include red and black grapes (grape skin contains polyphenols [anthocyanins and leucoanthocyanins], while
