摘要
本研究应用分光光度法和高效液相色谱法测定了4种不同茶叶的化学成分和儿茶素的含量,结果表明,茶叶品种不同,其化学成分、儿茶素的组成与配比差异较大,这是决定其抗癌作用的物质基础。
Chemical compositions and their contents of catechins in 4 different tea were determined by spectrophotometry and high performance liquid chromatography （HPLC）. The results show that chemical compositions, contents of catechins and their ratios were greatly different in different varieties of tea, which are the substance bases that determine the antitumor function of tea.
