Diterpenoids from Salvia ceratophylla

Salvia ceratophylla L. has yielded four known and two new diterpenoids together with two triterpenic acids, a steroid and a flavone. The structures of the compounds were established by spectroscopic analyses. One of the known compounds candidissiol exhibited a high antibacterial activity against Staphylococcus epidermidis and Proteus mirabilis.     

Kaurane-Type Diterpenoids from Liverworts

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-14α-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-4β, 10α-dihydroxyaromadendrane.     

Diterpenoids of Isodon macrophylla

Two new ent‐abietane diterpenoids, macrophynin E ( 1 ) and macrophynin F ( 2 ), and a known related ent‐abietanoid (?)‐lambertic acid ( 3 ), together with four known ent‐kauranoids, were isolated from the roots and aerial parts of Isodon macrophylla, respectively. The structures of the new compounds were elucidated on the basis of spectroscopic‐data analysis and chemical correlations.
