Article abstract of DOI:10.1016/S0040-4039(00)73524-6

Five novel labdane-type diterpenoids, named ptychantins A-E, closely related to forskolin have been isolated from the liverwort Ptychanthus striatus, and their absolute structures established by a combination of high resolution NMR and CD spectra, X-ray crystallographic analysis and chemical degradation.
