摘要
[目的]分析以茶多酚为亲核剂的木瓜原花青素降解反应产物。[方法]采用液相色谱-电喷雾质谱联用技术(LC-ESI-MS),分析主要降解反应产物。[结果]3个新产物的结构分别推测为(表)儿茶素-(4-8)-(表)没食子儿茶素、(表)儿茶素-(4-8)-(表)没食子儿茶素3-O-没食子酸酯和(表)儿茶素-(4-8)-(表)儿茶素3-O-没食子酸酯。[结论]该研究为木瓜原花青素降解产物进一步在医药品、保健食品、食品添加剂和化妆品等领域上的应用奠定基础。
[Objective] The study aimed to analyze the degradative products that was from the degradative reaction of quince polymeric proanthocyanidins with tea polyphenols as a nucleophile.[Method] LC-ESI-MS technique was adopted to analyze the structures of the main degradative products.[Result] Three new products were deduced as（epi）catechin-（4-8）-（epi）gallocatechin,（epi）catechin-（4-8）-（epi）gallocatechin 3-O-gallate,and（epi）catechin-（4-8）-（epi）catechin 3-O-gallate.[Conclusion] The results could provide scientific basis and support for the further application of the new type antioxidant oligomeric proanthocyanidins in the fields of pharmaceuticals,health foods,food supplement and additives,and costimetics,etc.
