Highly oxygenated labdane-type diterpenoids, ptychantins from cultured cells of the Ptychantus striatus liverwort.
One novel labdane-type diterpene, named ptychantin O, and two known diterpenes, ptychantin G and F, were isolated from cultured cells of the Phychanthus striatus liverwort, and their structures were determined by NMR spectroscopic analyses.
