title: Sesquiterpene hydrocarbons from the liverwort Treubia isignensis var. isignensis with chemotaxonomic significance.
abstract: The New Caledonian endemic Treubia isignensis var. isignensis, which is known as a morphologically primitive liverwort, was extracted with diethyl ether and the crude extract analyzed by TLC and GC/MS. The species is chemically very primitive because it produces only maaliane-, eudesmane-, aristolane and gorgonane sesquiterpene hydrocarbons, which are significant chemical marker of the species; neither oxygenated terpenoids nor aromatic compounds were detected.
