A new rosane diterpenoid, 3a-hydroxy-5,15-rosadien-11-one (3), was isolated, together with a known rosane diterpenoid, 5,15-rosadiene-3,11-dione (4), and an aromadendrane sesquiterpenoid, ent-cyclocolorenone (5), from the Et(2)O extract of an unidentified Argentine liverwort Anastrophyllum species. Moreover, four known sesquiterpene lactones 6-9 and two known bibenzyls 10, 11 were isolated from the Et(2)O extracts of Argentine Frullania brasiliensis and Radula voluta, respectively. The structures of compounds 3-11 were determined by the use of NMR techniques.
一种新的罗莎二萜，3a-羟基-5,15-罗莎二烯-11-酮（3），与一种已知的罗莎二萜，5,15-罗莎二烯-3,11-二酮（4）和一种芳香单萜倍半萜，环柯罗烯酮（5）一起从阿根廷一种未鉴定的肝叶苔属 Anastrophyllum 物种的 Et(2)O 提取物中分离出来。此外，还从阿根廷 Frullania brasiliensis 和 Radula voluta 的 Et(2)O 提取物中分别分离到了四个已知的倍半萜内酯 6-9 和两个已知的二苄基 10, 11。化合物 3-11 的结构通过 NMR 技术确定。
