Alkaloid-Derived Mlecules low rank argonne premium coals

摘要

Molecules that are probably derived from alkaloids have been found in the extracts of the subbituminous and lignite Argonne Premium Coals.High reslutioin mass spectrometry (HRMS) and liquid chromatography mas spectrometry (LCMS) have been used to characterize pyridine and supercritical extracts.The supercritical extraction used an approach that has been sucessful for extracting alkaloids from natural products.The first indication that there might be these natural products in coals was the large number of molecules found containing multiple nitrogen and oxygen heteroatoms.These molecules are much less abundant in bituminous coals and absent in the higher rank coals.
