    Phenolic acid(酚酸)是一種含有酚環結構的有機酸,其核心特征是一個或多個羟基(-OH)直接連接到芳香烴環上。以下是詳細解釋:

    1. 化學定義

      • 屬于酚類化合物(Phenolic compounds)的亞類,分子結構由苯環上的羟基和羧酸基團(-COOH)組成。例如,水楊酸(鄰羟基苯甲酸)是典型的酚酸。
    2. 分類與常見類型
      根據羟基和羧酸基團的位置差異,可分為:

      • 羟基苯甲酸類:如香草酸、原兒茶酸;
      • 羟基肉桂酸類:如咖啡酸、阿魏酸。
    3. 天然來源與功能

      • 廣泛存在于植物中,如水果(藍莓)、蔬菜(洋蔥)、草藥和谷物。具有抗氧化、抗炎特性,是植物防禦系統的重要成分。
    4. 應用領域
