Six new compounds, including two diterpenoids excocarinols F and G (1 and 2, resp.), two carotane (daucane) sesquiterpenoids excoecafolinols A and B (3 and 4, resp.), one lignanoid compound, excoecanol A (5), and one simple phenol, excoecanol B (6), together with 17 known compounds, were isolated from the BuOH extract of Excoecaria acerifolia Didr. stems. Their structures were elucidated through the analysis of the spectroscopic data. The AChE-inhibitory activities of 17 compounds were evaluated and revealed that four of them possessed moderate inhibitory activities against AChE.
