摘要： 采用茶多酚与松树皮原花青素进行片段化反应,形成了3个新的片段化产物,通过LC-ESI-MS联用技术分析获得了它们的相对分子质量信息,并推测出它们的化学结构分别为(表)儿茶素-(4β-8)-(-)-表没食子儿茶素-3-O-没食子酸酯、 (表)儿茶素-(4β-8)-(-)-表儿茶素-3-O-没食子酸酯和(表)儿茶素-(4β-8)-(+)-没食子儿茶素-3-O-没食子酸酯。

关键词: 松树皮原花青素, 片段化产物, LC-ESI-MS

Abstract: The fragmentive products of pine bark proanthocyanidins were analyzed by LC-ESI-MS technique. Three new products were formed from the fragmentive reaction with tea polyphenols as a nucleophile. Their structures were deduced as (epi)catechin-(4β-8)-(-)-epigallocatechin-3-O-gallate (2), (epi)catechin-(4β-8)-(-)-epicatechin-3-O-gallate (1), and (epi)catechin-(4β-8)-(+)-gallocatechin-3-O-gallate (3).

Key words: pine bark proanthocyanidins, fragmentive products, LC-ESI-MS
