摘　　要：在琼东南盆地的凝析油和煤系泥岩中发现高丰度的未知物，据GC／MS分析的保留时间和质谱图初步鉴定为树脂化合物W、T，进一步运用GC／MS／MS分析方法获得化合物T的质谱信息与双杜松烷分子结构吻合。并且运用GC／MS／MS手段在珠江口盆地鉴定出双杜松烷型的树脂化合物，排除了对甾烷的干扰。双杜松烷及其同系物对指示这些地区的生源物质及沉积环境有特殊意义。Unkown compounds of high abundance were found in the condensates and mudstones of coal bearing series in Qiongdongnan basin. They were initially indentified as resin compounds W,T,from the retention time of GC/MS analysis. Further application of GC/MS/MS analysis technique found the mass spectrogram of resin compound T coincided with the molecular structure of Bicadinane. Resin compounds of Bicadinane type were also identified in Pearl River Mouth Basin with GC/MS/MS technique. Therefore its disturbance on sterane was obliviated. Bicadinane and its family have special importance on the source materials and sedimentation envoirnment in these areas.
