Abstract:

A comprehensive chemical teaching experiment was introduced, including extraction, separation, identification and application of Indigo plants. The indigo was extracted from Isatis root and applied to dying. The experiment involves several basic methods of natural product extraction, analytical chemistry procedures and its application. Through the experiment, students' research interest and exploring spirit will be stimulated, and experiment operation skills will be improved. This experiment was expected to be taught through lively activities, and outlined the relation between basic operation and production application.
