蒙顶茶中的儿茶素及氨基酸分析

摘要

以4种蒙顶茶为材料,采用高效液相色谱法分析了蒙顶茶的氨基酸及儿茶素组成含量.结果表明,蒙顶茶中儿茶素总量为12.91％～15.75％,其中EGCG含量最高,含量为6.67％～9.20％；蒙顶茶中氨基酸总量为3.456％～4.102％,其中茶氨酸含量为1.983％～2.372％.%The content of total catechin and amino acids in four kinds of Mengding tea was analyzed by HPLC. The results showed that the content of total catechin was 12.91%~15.75% among which the content of EGCG was the highest (6.67%~9.20%). The content of total amino acids in four tea was 3.456%~4.102% among which the theanine content was 1.983%~2.372%.
