为了研究萜类化合物的早期演化特征,对松柏类有机质样品进行了长期(超过5年)的低温(80℃)模拟实验研究.使用色谱和色谱-质谱联用技术,测定了样品模拟早期(1年)和模拟后期(5年半)的饱和烃组成特征,实验结果表明萜类化合物和直链烷烃在沉积后发生了明显的早期演化.利用质谱鉴定出了地质体中较少报道的两种杜松四烯,一种松香四烯和三种降松香四烯等中间演化产物.据此给出了相对完整的杜松类倍半萜和松香类三环二萜的早期演化途径,发现该过程主要生成了萜类的各种芳构化衍生物,细菌等微生物应起到了重要的生物化学促进作用.
In order to study the early evolution characteristics of terpenoids, the long-term (more than 5 years) simulation experiments of coniferous organic matter samples at low temperature (80 ℃) were carried out.Using chromatographic and mass spectrometry coupled with mass spectrometry, Year) and later period (5 years and a half years), the experimental results show that the terpenoids and linear alkanes evolve obviously after the deposition, and the two types less reported in the geological body have been identified by mass spectrometry Juniperne, a rosin tetraene and three downdoxene intermediates and other intermediate products.According to the relatively complete juniper sesquiterpene and rosin tricyclic diterpenes early evolution pathway found that the The process mainly produces a variety of aromatic derivatives of terpenoids, bacteria and other microorganisms should play an important role in biochemical promotion.
