采用乙醚萃取法提取墨西哥、厄瓜多尔、希腊、德国和日本的21种苔类植物，并对粗提物进行薄层色谱和GC/MS分析。鉴定出几种挥发性倍萜类和二萜类，以及联苯类。这些化合物中有许多是苔属或科的重要化学标记物。双糖烷型二萜二醛存在于贝壳科植物中，而联苯类，特别是带一个戊烯基的联苯类是日本Radula perrottetii的特征。eudesman型倍半萜类内酯和pinguisane型倍半萜类分别是柽柳果螨（Frullania tamarisci）和沙山恙虫（Trocholejeunea sandvicensis）的显著标记物。希腊的Fossombronia anglosa含有与之前在褐藻中发现的完全相同的化合物。这种化学相似性表明，一些苔类和藻类可能具有进化关系。
Twenty-one liverworts from Mexico, Ecuador, Greece, Germany and Japan were extracted with diethyl ether and the crude extracts analyzed by TLC and GC/MS. Several volatile sesqui- and diterpenoids, and also bibenzyls were identified. Many of these compounds are important chemical markers of liverworts genus or family. Sacculatane-type diterpene dialdehydes occur in the Pelliaceae family, while bibenzyls, especially with a prenyl group are characteristic of the Japanese Radula perrottetii. Eudesman-type sesquiterpene lactones and pinguisane-type sesquiterpenoids are significant markers of Frullania tamarisci and Trocholejeunea sandvicensis, respectively. The Greek Fossombronia angulosa contained exactly the same compounds previously found in brown algae. Such chemical similarity suggests that some families of liverworts and algae may have an evolutionary relationship.
