Ageratina ixiocladon afforded several p-hydroxyacetophenone derivatives and diterpenes including six new ent-clerodanes. Two further species, which are also placed in the subgenus Ageratina, gave p-hydroxyacetophenone derivatives which seem to be characteristic for this group. The structure were elucidated by high field 1H NMR techniques.
