| 摘 要： | "从茶叶中提取咖啡因"是大学有机化学实验教学中关于天然产物提取的经典实验,特别是对化学专业、生物专业、农学专业来说,更是必做不可。但由于该实验过程有一定难度,从而在实验教学中经常出现无产物等现象。为此,文章讨论了从茶叶中提取咖啡因的教学方法,阐述红茶与绿茶中咖啡因的提取条件及数据探索,利用索氏提取方法比较红茶与绿茶中咖啡因的产率,从而比较红茶与绿茶中咖啡因的含量,提出红茶为"茶叶中咖啡因的提取"实验选择最佳茶叶,提高了实验的成功率。

| Abstract: | Caffeine Extraction from Tea is a classical undergraduate organic chemistry experiment, which is about natural products extraction.This experiment is a compulsory course not only for chemistry and biology majors but for agronomy majors as well.But due to certain difficulty in the route of conducting the experiment,it is commonly seen that no caffeine is produced during the process.Therefore,this paper describes the teaching methods for extracting caffeine from tea leaves,discusses the extraction condition a... |
