A new diterpenoid ester, fritillahupehin (1) together with three known fatty acids: palmitic acid (2), lignoceric acid (3) and azelaic acid (4) were isolated from the bulbs of Fritillaria hupehensis Hsiao and K.C. Hsia. The structure of fritillahupehin has been established to be ent-kauran-16β-yl lignocerate by means of spectroscopic and chemical evidence. Compounds 2-4 were isolated from Fritillaria sp. for the first time.

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.
