| 摘 要： | 利用高效液相色谱法分别测定表没食子儿茶素没食子酸酯、表儿茶素、茶氨酸、槲皮素、黄嘌呤和次黄嘌呤在普洱茶发酵过程中的含量变化，发现在发酵过程中，表没食子儿茶素没食子酸酯、表儿茶素、茶氨酸和槲皮素的含量下降，黄嘌呤和次黄嘌呤的含量上升。对这6种成分进行了相关性分析，发现多酚类与氨基酸类呈极显著正相关。

| Abstract: | High performance liquid chromatography (HPLC) has been employed for the determination of epigallocatechin gallate, epicatechin, theanine, quercetin, xanthine and hypoxanthine during the pile fermentation of Pu’er tea. It was found that during the fermentation process, the content of epigallocatechin gallate, epicatechin, theanine and quercetin decreased continuously, whilst the content of xanthine and hypoxanthine increased. Correlation analysis has been established for the six compositions. A significant positive correlation was found between polyphenols and amino acids. |
