辣椒红素（英语：capsanthin）是一种从辣椒属果实中提取出来的一种深红色脂溶性物质，分子式C₄₀H₅₆O₃，属于叶黄素，是辣椒显深红色的主要因素，用于食品着色剂。辣椒提取物（Paprika oleoresin，paprika extract）的组分还包括辛辣来源的辣椒素，另一种主要着色物辣椒玉红素，还有β-胡萝卜素和其它类胡萝卜素。

提取辣椒红素使用己烷等有机溶剂，各种组分可通过柱色谱分离，溶剂在使用前除去。

Paprika oleoresin (also known as paprika extract) is an oil-soluble extract from the fruits of Capsicum annuum or Capsicum frutescens, and is primarily used as a colouring and/or flavouring in food products. It is composed of capsaicin, the main flavouring compound giving pungency in higher concentrations, and capsanthin and capsorubin, the main colouring compounds (among other carotenoids).
