Capsorubin is a red xanthophyll carotenoid pigment found in Capsicum annuum fruits. It contributes to paprika's color and serves as a natural food colorant (E160c). Derived from zeaxanthin via oxidative cleavage, it exhibits antioxidant activity by quenching singlet oxygen. The compound features a conjugated polyene chain with two cyclopentane rings bearing keto and hydroxy groups, conferring stability and fat solubility. Used in food, cosmetics, and supplements for its vibrant hue and potential health benefits including anti-inflammatory effects.
