[Catecholamines in the sub-esophageal ganglia and the hemolymph of the giant African snail (Achatina fulica Férussac) determined by gas chromatography].

The content of three catecholamines (dopamine, L-norepinephrine and L-epinephrine) in the subesophageal ganglia and the hemolymph of Achatina fulica Férussac was measured by a gas chromatograph with electron capture detector. The dopamine content of the ganglia was 4.3 +/- 0.9 mug/g. L-Norepinephrine and L-epinephrine in the ganglia were not detected. The three catecholamines in the hemolymph were also not detected.
