• Two new labdane-type diterpenoids were isolated from the EtOH extract of the herb of Leonurus japonicus. Their chemical structures were determined by the analysis of 1D, 2D NMR, and HRESIMS, and by comparing with known analogs. Two new labdane-type diterpenoids, 5-ethoxy-3-(2-((R)-4-hydroxy-2,5,5,8a-tetramethyl-3-oxo-3,5,6,7,8,8a-hexahydronaphthalen-1-yl)ethyl)furan-2(5H)-one (1), and 5-hydroxy-4-(2-((1R,3S,7aS)-1-hydroxy-4,4,7a-trimethyl-3-propionyloctahydroisobenzofuran-1-yl)ethyl)furan-2(5H)-one (2), were isolated from the EtOH extract of the herb of Leonurus japonicus Houtt., Lamiaceae. Their chemical structures were determined by analysis of 1D, 2D NMR, HRESIMS, and by comparison with known analogs.
