In a course of our studies on chemical constituents from Hepaticae, three new sesqueterpenoids were isolated together with cuparene from the liverwort, Bazzania pompeana (Lac.) Hitt. These compounda were named bazzanene ε-cuparenol and bazzanenol and their structures were respectively determined as 2,6,6-trimethyl-8-methylene bicyclo[5.3.1]undec-2-ene (II), 2-methyl-5-(1,2,2-trimethylcyclopentanyl)phenol (III) and 2,6,6(-trimethyl-8-methylene bicyclo[5.3.1] undec-2-en-4-ol (IV) by chemical and spectrometrical methods.
