EGCG-O-甲基转移酶(EOMT)催化EGCG形成的EGCG甲基化衍生物分析
Analysis on the EGCG Methylated Derivatives Produced from EGCG Catalyzed by EGCG-O-Methyltransferase
摘要
Abstract
The fragmentation pathways of EGCG3"Me, EGCG4"Me and EGCG3'Me were studied using LC-MS under positive ionization mode, and the EGCG methylated derivatives produced from EGCG catalyzed by EGCG-O-Methyltransferase were analyzed. Results showed that more than ten kinds of EGCG methylated derivatives were identified, including EGCG3"Me, EGCG4"Me, EGCGS'Me, EGCGS'Me, EGCG3",4"-diMe, EGCG3",5"-diMe, EGCG3',5'-diMe, EGCG3',5"-diMe, EGCG3',3",5"-triMe, EGCG5',3",5"-triMe.关键词
