以粗老茶叶为原料，超声辅助提取其中的茶氨酸，用分光光度法测试含量，考察超声提取温度、超声作用时间和浸提剂的用量对提取率的影响。正交试验表明，以水为浸提剂，在温度60℃、时间30min、固液比为1：50时浸提效果最好，浸提率为1．91％。该方法具有简便、有效和节约能耗等特点。

Ultrasound-assisted extraction technology was used to extract L-Theanine from coarse tea. Spectrophotometry was adopted to measure the content, and to observe the effects of extracting time, temperature, amount of extracting agent on the theanine extraction rate. The result indicated that with water as extracting agent, the extracting effect was best when the optimum process was 60 ~C; ultrasound extracting time was 30min; solid liquid ratio was 1:50; and the extraction rate was 1.91%. The method is characterized by simplicity, effectiveness, and energy saving.
