The red cabbage pigment is used as a teaching material for acid alkaline experiment in lower secondary school science. However, it is difficult to obtain the red cabbage stably throughout the year. Thus, in the present study, to develop a new teaching material for acid alkaline experiment, the extraction method of pigment from eggplant and the color development at each pH of the pigment extracted were examined. Furthermore, the color development at each pH of the pigment extracted from the several eggplants were compared.
