中文摘要:

      茶叶作为主要饮品之一, 对茶叶品质评定是必不可少的一个过程。茶叶的品质除了感官评定其色、香、味, 还可通过测定其茶多酚、氨基酸、矿物质、蛋白质、生物碱等活性成分的综合含量来评定。生物碱是茶叶中的主要活性成分之一, 不仅决定着茶叶的品质, 对人体也具有一定的有益作用。生物碱的快速、高效检测方法是茶叶品质评估和茶叶中生物碱提取及含量检测的前提和关键。本文参考了国内及国外对茶叶中生物碱研究方法的相关文献, 对茶叶生物碱(主要是咖啡碱、可可碱、茶叶碱)最主要的检测方法进行了综述。为进一步研究茶叶中生物碱及测定其含量, 评估茶叶的品质提供参考。

英文摘要:

      As one of the main drinks, tea quality assessment is an essential process. In addition to the senses to assess its color, aroma, taste, but also by measuring the comprehensive content of its tea polyphenols, amino acids, minerals, proteins, alkaloids and other active ingredients to be assessed. Alkaloid is one of the main active ingredients in tea, which not only determines the quality of tea, but also has a beneficial effect on the human body. The fast and efficient alkaloid testing method is the premise and key of tea quality assessment and alkaloid extraction and content detection in tea. In this paper, the research progress of tea alkaloids (mainly caffeine, theobromine and theophylline) was reviewed by referring to the domestic and foreign literatures on the research methods of alkaloids in tea leaves. In order to further study the alkaloid in tea, determine its content and evaluate the quality of tea.
