Seven kaurane-type diterpenoids were isolated from the Taiwanese liverworts Jungermannia truncata. Among them, three are new structures. They are: ent-16-kauren-3,15-dione(6), ent-16(S)-kauran-3,15-dione (7), and ent-14.alpha.- hydroxy-16-kauren-15- one (11). From Plagiochila pulcherrima, three known kaurane alcohols were also isolated along with sesquiterpenoids plagiochilines A, B, C and ent- 4.beta.,10.alpha.-dihydroxyaromadendrane.
