Abstract:The distribution of ent-2,3-secoaromadendrane-, ent-aromadendrane-, ent-bicyclogermacrane- and ent-maaliane-type sesquiterpenoids in fourteen Plagiochila species is described. These sesquiterpenes are the significant chemosystematic markers of Plagiochila. The intense pungent substance of some Plagiochila species is due to an ent-2,3-secoaromadendrane-type sesquiterpene hemiacetal, plagiochiline A.
