Two new furanic diterpenoids, 1-((2S)-2-(3-(furan-3-yl)propanoyl)-2,6,6-trimethylcyclo-hexyl)- 2-hydroxybutan-1-one (1), and 1-((1S,3R,3aS)-3-(2-(furan-3-yl)ethyl)-3-methoxy-3a,7,7- trimethylocta hydroisobenzofuran-1-yl) propan-1-one (2), together with three known ones seco-labdane (3), 6β-hydroxy- 15,16-epoxy-labda- 8,13(16),14- trien-7-one (4), and leojaponin (5) were isolated from the herb of L. japonicus. Their structures were determined by 1D and 2D NMR data.
