Anthocyanidin

Anthocyanidins are common plant pigments, usually red or blue or variations on those colors, that have antioxidant, antiplatelet, and wound-healing properties. They are the sugar-free counterparts of anthocyanins. Anthocyanidins are a type of flavonoid, a potent substance with antioxidant activity, which may help fight heart disease and cancer. They are found in cranberries and many other brilliantly colored fruits and vegetables.
