木瓜多聚原花青素降解产物的液相色谱-电喷雾质谱分析
LC-ESI-MS Analysis of Degradative Products of Quince Polymeric Proanthocyanidins
摘要
Abstract
The study aimed to analyze the degradative products that was from the degradative reaction of quince polymeric proan-thocyanidins 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)gallo-catechin 3-0-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.关键词
