摘要：

Four novel highly oxygenated labdane-type diterpenoids, named ptychantins F-I (1-4) have been isolated from the liverwort Ptychanthus striatus, and their structures including their absolute configurations established by a combination of high resolution NMR and CD spectra, X-ray crystallographic analysis, and chemical degradations.
