Abstract

The structures of two new ent-kaurane diterpenoids and two derivatives of shikokianin isolated from leaves of Isodon leucophyllus were elucidated by 1D and 2D NMR techniques as 11α-acetoxyeffusanin D (1), 6-acetylepinodosinol (2), 16β-ethoxymethyleneshikokianin (3), and 16α-ethoxymethyleneshi-kokianin (4).
