吉林陨石中有机色素和卟啉化合物的初步研究

This paper discribes the extraction of porphyrin compounds and related pigments from Jilin meteorite with 9:1 (v/v) benzene and methanol mixture. After removal of sulfur and asphalts the hexane solution of the extract is eluted through a silica jel chromatographic column with hexane, benzene, and acetone successively.Nickel porphyrin, vanadium porphyrin and chlorins are found in the benzene eluate and their content are estimated to be 0.008 ppm, 0.006 ppm and 0.002 ppm respectively.The aliphatie hydrocarbons in the meteorite are estimated to be approximately 74pp.The results are summarized and discussed.
