Abstract: Adopts high performance liquid chromatography to analyse the kinds and content of glycosidic alkaloid in root，stem，leaves，pedicle in eggplant，the results show that the 4 non-eating section of eggplant all contain 3 glycosidic alkaloid which are α-solanine，α-chaconine and α-solasonine，the content of each glycosidic alkaloid in each place is statistical significance（P<0. 05），the content distribution of α-solanine is pedicle>leaves>root>stem，α-chaconine is root>stem>leaves>pedicle，α-solasonine is root>stem>pedicle>leaves，the total content of glycosidic alkaloid is pedicle>root>leaves>stem. The research lays a foundation for overall development and utilization of non-eating part of eggplant.

Key words: eggplant, high performance liquid chromatography, glycoalkaloid
