| Abstract: | The extraction of caffeine from tea is a basic organic experiment,which is a classic teaching case about the natural ingredients extracted from plants.According to the observation of students' experimental process,pondering on the experimental results and searching literature,we have analysed several factors about extracting caffeine and explored these factors by orthogonal experiment,which reaches a optimum route in extracting caffeine from tea. |
