摘要：

gamma -Aminobutyric acid (GABA), a hypotensive compound, is formed from glutamic acid under anaerobic condition in tea shoots. Glutamic acid was exhausted in the first three hours of anaerobic incubation and the increase of GABA stopped. After that, when tea shoots were released under aerobic condition, glutamic acid reproduced rapidly. After one hour of aerobic incubation, tea shoots were given three hours of anaerobic incubation again and then accumulated glutamic acid changed to GABA. The content of GABA increased much more than usual anaerobic incubation. GABA was more in the tea stem than in the leaf.
