title: Herbertane-type sesquiterpenoids from the liverwort Herbertus sakuraii.
abstract: Seven herbertane-type sesquiterpenoids, 1,13-dihydroxyherbertene, 1,14-dihydroxyherbertene, 1,15-dihydroxyherbertene, 12-methoxyherebertene-1,2-diol, herberteneacetal, herbertenone A and herbertenone B were isolated from the Japanese liverwort Herbertus sakuraii, together with four known herbertane- and three dimeric herbertane-type sesquiterpenoids and ent-pimara-8(14),15-dien-19-oic acid. Their structures were elucidated by spectroscopic methods. H. sakuraii is chemically similar not only to H. aduncus but also to the Mastigophora species.
