S(R)()-Podolactone D (1), a new norditerpene dilactone having a methylsulfoxide moiety, was isolated from the leaves of Podocarpus macrophyllus D. Don var. maki Endl. along with known podolactone D (2, S(S)()-podolactone D). The structures and absolute configurations of compounds 1 and 2 were
Fourteen new bisnor- and norditerpene dilactones, makilactones E-R, having a 7alpha : 8alpha-epoxy-9,11-enolide substructure, were isolated from a methanolic extract of the root and the bark of Podocarpus macrophyllus D. DON (Podocarpaceae) with thirteen known bisnor- and norditerpenoids, and the
