Abstract 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.
