Abstract Three new fusicoccane-type diterpenoids, fusicogigantone A, fusicogigantone B and fusicogigantepoxide, a new dolabellane-type diterpenoid, 18-hydroxy-4,8-dolabelladiene and a new rearranged labdane-type diterpenoid, pleurodiol have been isolated from the ether and the methanol extract of the liverwort Pleurozia gigantea together with the previously known (−)-3,14-clerodadien-13-ol, 14-labden-8
摘要 三种新的fusicoccane-type diterpenoids,fusicogigantone A,fusicogigantone B和fusicogigantepoxide,一个新的dolabellane-type diterpenoid,18-hydroxy-4,8-dolabelladiene和一个新的重排的labdane-type diterpenoid,从pleurodiol中分离出来。地草的甲醇提取物 Pleurozia gigantea 连同先前已知的 (-)-3,14-clerodadien-13-ol、14-labden-8,13-diol、ent-kaurene 和 spathulenol 及其结构由 NMR 光谱数据阐明和化学相关性。Pleurozia gigantea 是一种化学上比 P. acinosa 更先进的物种。
