Abstract: Palaeophytochemical investigation of the Pliocene-fossil wood of Tsuga dumosa found in brown coal led to the detection of 22 volatiles and the isolation of 9 compounds (1 - 9) , including six types of n-alkanes (C16 up to C32 ), fatty acids, steroids, triterpenoids, phthalates and aromatic compounds . Their structures were elucidated on the basis of spectroscopic
evidence .

Key words: Pliocene-fossil

摘要： 为了研究在褐煤中发现的上新世云南铁杉(Pliocene Tsuga dumosa) 木化石的化学成分, 采用气相色谱-质谱联用技术和柱层析方法分别检测了22 个挥发性成分和分离鉴定了9 个化合物(1 - 9) , 化学成分类型包括烷烃(C16 -C32 )、脂肪酸、甾体、三萜、邻苯二甲酸酯及酚性成分。化合物结构采用波谱方法鉴定。
