摘要
采用HPLC-DAD-MS/MS技术对英红1号、英红9号和祁门茶树的芽叶进行了分析,鉴定出了2种嘌呤生物碱,7种儿茶素类化合物以及2种非儿茶素类茶多酚。对这3个茶树品种的嘌呤生物碱和儿茶素类成分质量分数进行比较分析,结果表明三者的儿茶素类总质量分数均大于20%,其中英红1号和祁门红茶品种在儿茶素类成分的组成上较为接近,EGCG质量分数均为最高;而英红9号质量分数最高的是ECG。
Using the HPLC-DAD-MS/MS method, two purine alkaloids, seven catechins, and two noncatechin type of polyphenols were identified in young leaves of Yinghong 1, Yinghong 9 and Qimen cuhivars mainly made for black tea. According to the quantitative results, the contents of catechins in the leaves of Yinghong 1 and Qimen are similar, while Yinghong 9 is quite different, with ECG higher than EGCG.
