Analysis for sulfur compounds in lipid extracts from the orgueil meteorite

Solvent extracts of the Orgueil carbonaceous meteorite were investigated by thin-layer chromatography, ultraviolet, infrared, and mass spectrometry, and by ultramicro elemental analysis for sulfur. Long chain thiols were absent but trace amounts of open-chain sulfides and some heterocyclic compounds containing sulfur appear to be present in the meteorite lipid fraction. The conditions for the formation of the sulfur compounds are in agreement with the generally accepted concepts regarding the environment of the meteorite parent body (ies). The meteorite lipid fraction appears to differ in part from petroleum.
