Abstract: | The volatile components of 25 taxa of the liverwort family Frullaniaceae from New Zealand, Australia and South America have been analyzed by GC-MS. The present Frullania species are chemically divided into five major types: (1) sesquiterpene lactones, (2) sesquiterpene lactones-bibenzyls, (3) bibenzyls, (4) 2-alkanone and (5) triterpene types; the latter two chemo-types are newly proposed for the genus. Schusterella chevalierii, belonging to the Frullaniaceae, is closely related chemically to the sesquiterpene lactone type of the Frullania species since it elaborates two eudesmanolides, beta-cyclocostunolide and dihydro-beta-cyclocostunolide as major components. |
