Constituents of the liverwort Bazzania trilobata of Czech origin

Abstract

From Bazzania trilobata of Czech origin a series of sesquiterpenoids were obtained as products identical with those described in a recent paper from the same species of Japanese origin, namely α- and β-barbatene, bazzanene, cuparene, calamenene, 5-hydroxy- and 7-hydroxycalamenene, and drimenol. Furthermore we obtained ledene, gymnomitrol, gymnomitrone and viridiflorol as new components for this plant. A detailed study of the wax components was performed, too. A study of seasonal variations of the essential oil content and of its composition is presented.
