In order to control the formation condition of oxidation oligomers of flavanols,epigallocatechin-3-gallate(EGCG) was oxidized in vitro and EGCG oligomeric products(EOP) were determined by HPLC-MS analysis.
为控制儿茶素类低聚氧化产物形成条件,以表棓儿茶素棓酸酯(EGCG)为代表进行体外化学氧化,通过对产物的HPLC-MS分析确定研究对象,即EGCG氧化低聚物(EOP),其主要有3种低聚产物:产物1m/z911,产物2m/z 929,产物3m/z911。
