Abstract The amino acid composition of the protein of the wing muscle of the African migratory locust ( Locusta migratoria migratorioides ) was examined by qualitative and quantitative methods. the possible presence of lanthionine was investigated. Lanthionine could not be detected by two‐dimensional paper chromatography nor by ion‐exchange chromatography operated under three different conditions of temperature and pH. the analysis of hydrolysates prepared after a preliminary oxidation revealed no changes in composition that would arise had lanthionine been present together with other acids.
