松树皮原花青素片段化产物的LC-ESI-MS分析
LC-ESI-MS Analysis of Fragmentive Products of Pine Bark Proanthocyanidins
摘要
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(43-8)-(-)-epigallocatechin-3-O-gallate (2),(epi) catechin-(4β-8)-(-)-epicatechin-3-O-gallate (1),and (epi) catechin(4β-8)-(+)-gallocatechin-3-O-gallate (3).关键词
