Three new sesquiterpenoids, striatene, striatol and β-monocyclonerolidol, were isolated from the liverwort Ptychanthus striatus(Lehm. et Lindemb.) Nees. Their structures have been established by spectroscopic analysis and chemical transformation.These compounds are interesting in terms of the evolution of the liverwort from algae.
从肝草 Ptychanthus striatus(Lehm. et Lindemb.) Nees 中分离出了三种新的
倍半萜化合物,即条纹烯、条纹醇和β-单环烯醇。这些化合物对于研究肝草从藻类进化而来的过程具有重要意义。
