Abstract

Abstract: A mass fragmentographic method for the simultaneous quantification of γ‐aminobutyric acid (GABA) and glutamic acid is described. In a convenient one‐step reaction, the two ammo acids were derivatized with pentafluor‐opropionic anhydride and pentafluoropropanol. The deri‐vatization products were stable for several days. The technique has been applied to the assay of GABA and Glu in five amygdaloid nuclei of the rat brain. The GABA level was high in the central and medial nuclei, whereas the Glu level was high in the lateral and basal nuclei. The regional distribution of GABA was different from that of Glu within the amygdaloid nuclei.
