Two new diterpenoids, named isodoternifolins A (1) and B (2), together with seven known compounds were isolated from the ethanol extract of dried stems and leaves of Isodon temifolius (D. Don) Kudo. The structures of 1 and 2 were determined as 7β-hydroxy-6β, 11α, 15β-triacetoxy-7α, 20-epoxy-entkaur-16-ene and 6β, 7β, 15β-trihydroxy-11α-acetoxy-7α, 20-epoxy-entkaur-16-ene by chemical and spectral evidence respectively.
