Abstract

Two new ent‐abietane diterpenoids, macrophynin E (1) and macrophynin F (2), and a known related ent‐abietanoid (−)‐lambertic acid (3), together with four known ent‐kauranoids, were isolated from the roots and aerial parts of Isodon macrophylla, respectively. The structures of the new compounds were elucidated on the basis of spectroscopic‐data analysis and chemical correlations.
