摘要
在一种泥盆系的角质残植煤中,检测出丰富的具扁枝烯和贝壳杉烯骨架的四环二萜化合物,其生源物可能是某些蕨类植物或是无环类异戊间二烯烷烃类被细菌改造的结果。
The analysis of coal--petrology and geochemistry were carried out for Devonian cuti-nite coal in Luquan Region, Yunnan, so that abundant tetracyclic diterpanoid with theskeletons of phyllocladene and kaurene were determined, but the contents of pristane andphytane were very little or nothing. According to paleoplant study, the coal-forming mate-rials were mainly the short plants of Psilopsid and Lycoposida. It is inferred that the tetra-cyclic diterpanes were not derived from the resinites which were considered from gym-nospermous, but may derived from pteridophytes or non-cyclic isoprenoid alkanes thatwere reformed by bacteria. This will be further studied in thermo-simulation of organicmatter.
