摘要
红紫芽茶富含花青素,具有较好的开发前景。应用高效液相色谱法测定比较6个红紫芽茶样品的花青素、儿茶素、咖啡碱等14种化学成分。从各样品中检测到6种花青素,含量最高的是矢车菊素,另外红紫芽3号和4号的花青素含量均高于紫娟的花青素;儿茶素含量最高的是红紫芽1号,并且6个样品的酯型儿茶素含量都高于简单儿茶素。试验初步揭示这6个红紫芽茶的化学物质组成,为进一步研究开发提供试验基础。
Purple tea shoots were rich in anthocyanins, and had a good development prospect. The contents of 14 components including anthocyanins, catechins and caffeine, etc. were detected in six purple tea shoots by HPLC method. Six anthocyanins with the highest content of cyanidin were detected in all samples. The contents anthocyanins in samples No.3 and No.4 were high that in Zijuan. The contents of catechin were highest in samples No.1. The contents of ester catechins were higher than that of simple catechins. The chemical compositions of six teas with purple shoots were revealed, and the experimental basis for the further research and development of the purple tea resources were provided.
