二咖啡酰酒石酸（英语：(2R,3R)-O-Dicaffeoyltartaric acid）菊苣酸（英语：Chicoric acid）又称西可酸（英语：Cichoric acid），是一种羟基肉桂酸，属于苯基丙酮类有机化合物，存在于多种植物物种中。它是咖啡酸和酒石酸的衍生物。^[1]

作为区分紫锥菊（Echinacea purpurea）物种的合适标记，它通常使用RP-HPLC和薄层色谱（TLC）方法进行检测。^[2]

来源

菊苣酸最早是从菊苣（Cichorium intybus）中分离出来的，但也大量存在于紫锥菊中，特别是紫锥菊、蒲公英叶、罗勒、柠檬香草和水生植物，包括藻类和海草。^[3]^[4]^[5]^[6]

生物学功能

在体外和体内研究中，菊苣酸都被证明可以刺激吞噬细胞，抑制透明质酸酶（一种在人体内分解透明质酸的酶）的功能，保护胶原蛋白免受自由基的损害，以及抑制HIV-1整合酶的功能。^[7]^[8]
