A new bisabolane-type sesquiterpenoid julaceal has been isolated from Anthelia julucea, together with the known terpenoids, ent-( -)-nuciferal, (-)-d-cuparenol and ent-168-hydroxykaurane, and its structure determined by extensive NMR techniques. The distribution of the known sesquiterpenoids in Plagiochila asplenioiodes, Riccardia chamedryfklia and Scapania crassiretis is discussed.
