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。

Abstract:

The analysis of coal-petrology and geochemistry were carried out for Devonian cutinite coal in Luquan Region, Yunnan, so that abundant tetracyclic diterpanoid with the skeletons of phyllocladene and kaurene were determined, but the contents of pristane and phytane were very little or nothing. According to paleoplant study, the coal-forming materials were mainly the short plants of Psilopsid and Lycoposida. It is inferred that the tetracyclic diterpanes were not derived from the resinites which were considered from gymnospermous, but may derived from pteridophytes or non-cyclic isoprenoid alkanes that were reformed by bacteria. This will be further studied in thermo-simulation of organic matter.
