Two new diterpene lactones from Roadgersia aesculifolia

Abstract The structures of two new diterpenoids isolated from ROADGERSIA AESCULIFOLIA Batyl (Saxifragaceae) have been determined by ID and 2D-NMR methods as 14α-hydroxy-7α-ethoxy-11,16-diketo-apian-8-en-(20,6)-olide (1) and 7α-hydroxy-11,16-diketo-apian-8,14(15)-dien-(20,6)-olide (2).
