| Résumé : | Honeybee brain extracts were subjected to a procedure of analysis on paper involving electrophoresis at two pH values, bidimensional chromatography and development with various reagents. This led to the identification of 18 aminoacids, a peptide (glutathione), a hydroacid (isethionic acid) and showed the presence of other as yet unidentified compounds : some aminoacids (one of which contained sulphur), some peptides, a guanidinic compound, one or more basic compounds reacting with ninhydrin, and one or more organic bases. An ion exchange chromatographic analysis substantially confirmed the results obtained on paper, and gave quantitative data on the individual aminoacids before and after hydrolysis. These results are discussed in relation to the data avaible from the literature on the aminoacid content of mammalian and invertebrate nervous tissue. |
