茶组植物中茶氨酸和没食子酸的高压液相色谱分析

HPLC Analysis of Theanine and Gallic Acid in the Species of Camellia sect.Thea

应用高效液相色谱(HPLC)技术对茶属茶组的6种3变种植物叶中的茶氨酸和没食子酸含量进行定量分析。结果表明,茶氨酸和没食子酸均普遍存在于这几种茶组植物中,二者在大理茶与广西茶中的含量与大叶茶最为接近,野生的大理茶在云南民间亦作为茶叶的原料使用,有悠久的历史,提示大理茶有可能是大叶茶的基源植物之一。

By means of HPLC technique, the theanine and gallic acid in the leaves of six species and three varieties of Camellia sect. Thea were analyzed. The results showed that both of them were generally occured in these plants and the contents in C. taliensis and C. kwangsiensis are mostly close to those of C. sinensis var. assamica. Since the leaves of C. taliensis have also been historically used for preparing tea by folk peoples of Yunnan province, it could be suggest that C. taliensis might one of the original plants of tea.
