摘要：

The diethyl ether extract of the Japanese livewort Frullania tamarisci subsp. obscura yielded a new sesquiterpene aldehyde in addition to a new dimeric sesquiterpenoid with a eudesmane-type carbon skeleton. Their structures were established by extensive 2D NMR techniques and chemical evidence. They were shown to be 4 alpha,6 alpha-dihydroxy-11(13)-eudesmen-12-al and its dimer with 4-epiarbusculin A at the C-4 ether linkage.
