(syn. Ammiopsis aristidis Batt.) (Apiaceae) from two locations (Ghoufi and Bousaada) in East of Algeria, was investigated for the first time by GC and GC-MS and evaluated for their in vitro acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activity, the enzymes linked to Alzheimer’s disease, by a spectrophotometric method of Ellman using ELISA microplate reader at 100 µg/mL. The main components of D. aristidis oils from Ghoufi and Bousaada were α-pinene (74.1%- 49%) and β-pinene (11.9% - 19.2%). This suggests that β-pinene was the main component from Bousaada. The oils exhibited a moderate inhibitory activity (over 50%) against both of the enzymes.
