Abstract:Two ent-isopimarane-type diterpenoids were isolated from the New Zealand liverwort Trichocolea mollissima (Hook. f. and Tayl.) Gott., together with a known 1alpha-hydroxy-ent-sandaracopimara-8(14),15-diene. Their absolute structures have been established by modified Mosher's method, X-ray crystallography and by analyses of their CD spectra.
Keywords:Trichocolea mollissima   Liverwort   Hepaticae   ent-Isopimarane-type   Diterpenoid
