Abstract In hot water extracts of samples from interior of two ordinary chondrites (Goumoshnik and Pavel) after acid hydrolysis using diphenylindonyl-isothiocyanate (DIITC) and fluorescent detection (FD) of the obtained diphenylindonyl thiohydantoins (ITH) 10 to 13 protein and nonprotein amino acids were found. In the same manner the presence of compounds containing amino groups but not of free amino acids was established in nonhydrolysed extracts. “Sequencing” was performed on the amino compounds using DIITC and FD of the cleaved ITH up to 9 steps with extracts of Goumoshnik and up to 14 with those of Pavel. At each step 1 to 6 different protein and nonprotein amino acids were liberated. The presence of nonprotein amino acids supports the view that the peptides in meteorites are indigenous.
