摘　　要：经用GC／MS、GC／MS／MS分析东海西部凹陷煤系烃源岩及凝析油样品，检测出12个二萜烷生物标志化合物。根据色谱保留时间、质谱特征及与文献资料对比，进一步确认其结构为：1个8β（H）－半日花烷，4个降海松烷，1个朽松木烷，1个异海松烷和5个四环二萜烷（即：ent-白叶烷，16α（H）－扁枝烷和16β（H）－扁枝烷，16α（H）－贝壳杉烷和16β（H）－贝壳杉烷）。异常丰富的二萜类化合物的检出，标志着树脂二萜对该区成烃的特殊贡献。Coal measures and condensate from Xihu Sag of East China Sea Basin are analysed by GC/MS and GC/MS/MS. Based on the retention time of GC, mass spectrum characteristics and compared with other literatures, twelve diterpanes, of which one 8β(H)-labdane, four norisopimarane, one fichtelite, one isopimarane, and five tetracylic (i. e. ent-Beyerane, 16α(H)-phyllocladane, 16β(H)-phyllocladane, 16α(H)-Kaurane and 16β(H)-Kaurane) are identified. Abnormally abundant diter-penoids compounds found in the condensate suggest that the important role of resinous diter-penoids during hydrocarbon generation in this region.
