摘  要:
对来自云南普洱茶主要产区的20个晒青毛茶进行研究,检测毛茶的多酚类总量、氨基酸总量、可溶性糖总量、咖啡碱等主要化学成分;利用高效液相色谱(HPLC)技术对毛茶的儿茶素进行分析;运用主成分分析的方法,对不同产地的毛茶进行动态聚类分析。结果表明,不同产地毛茶在主要化学成分组成上存在着差异性,同一地区毛茶基本一致,为普洱茶加工中发酵的控制及原料的拼配提供了一定的理论依据。

摘  要:
The main chemical composition of theanine,amino acids,the water-soluble carbohydrates,caffeine and other major chemical constituents in 20 Pu-erh crude teas from Yunnan was studied;Catechin were separated by high performance liquid chromatography(HPLC),and Pu-erh crude teas in different origins were polymerized through the major components.The results showed that there are significant different in chemical composition of Pu-erh crude teas from different origins,and the quality are similar from the same region.This investigation can supply fundamental data for processing and quality-assessment of pu-erh crude tea.
