Two new rearranged pinguisane-type sesquiterpenoids, spirodensifolin A and B, a pinguisane-type sesquiterpene, isonaviculol, and two new ent-kaurane-type diterpenoids, ent-kauran-16β-ol-3-one, ent-kaurane-3β,16β-diol, have been isolated from the Bolivian liverwort Frullanoides densifolia, and a pinguisane-type sesquiterpene, furanopinguisanol and lepidozane-type sesquiterpene alcohol have been isolated from the Japanese Trocholejeunea sandvicensis.Their stereostructures have been elucidated by the extensive analysis of the spectral data as well as the X-ray crystallographic analysis.Key Word Index - Frullanoides densifolia; Trocholejeunea sandvicensis; Lejeuneaceae; liverwort; Hepaticae; chemosystematics; spirodensifolin A; spirodensifolin B; furanopinguisanol; pinguisane-type sesquiterpenoids; ent-kauranols; kaurane-type diterpenoids; lepidozenol; lepidozane-type sesquiterpenoid.
