摘要
Preliminary investigation was earried out on the Jilin meteorite for hydrocarbonand nitrogen-bearing organic compounds. It shows that the meteorite contains 68 ppm of soluble organic matter, among which the normal alkanes amount to 0.36---0.48 ppm,with carbon number distribution ranging from C17 to C31, and the aromatic hydrocarbons herein are mainly composed of polyalkyl-substituted less condensed rings. Purine derivatives and pyrimidine have also been found. A discussion is given as to the origin of these organic substanees.
