General description
单咖啡酰酒石酸（CFA） 是一种多酚化合物，属于羟基肉桂酸（HCA）亚组。它是咖啡酸的衍生物。单咖啡酰酒石酸主要来源于紫锥菊。
Application
单咖啡酰酒石酸已被用于：
- 作为标准抗氧化剂采用 2,2-二苯基-1-苦基肼（DPPH）测定法测定红酒的抗氧化潜力 (AOP)
- 作为抗氧化剂与二氧化硫（SO2）一起用于通过 2,2-二苯基-1-苦基肼（DPPH）测定法和Folin-Ciocalteu （FC）法测定红酒的抗氧化潜力
- 评估其对以各种紫锥菊提取物处理的大鼠骨髓的骨髓细胞生成作用
- 鉴定康克葡萄汁中的（多）酚化合物以及饮用果汁后人血浆和尿液中的代谢物
Biochem/physiol Actions
单咖啡酰酒石酸对于吲哚美辛导致的大鼠胃溃疡具有抗氧化和抗炎作用。它还具有抗突变特性。
