Abstract

The present study provides the first information on the chemical composition and acetylcholinesterase inhibitory activity of the essential oil (EO) from the leaves of Mitrephora poilanei Weeras. & R.M.K.Saunders from Vietnam. Gas chromatography and gas chromatography-mass spectrometry analysis revealed that the main components of the M. poilanei EO were β-caryophyllene (13.2%), α-humulene (10.5%), germacrene D (8.1%), β-elemene (5.2%) and bicyclogermacrene (5.1%). The anti-acetylcholinesterase assay showed that the EO displayed moderate activity with IC50 value of 31.16 ± 3.06 μg/mL. These findings proposed that the plant can be exploited for its anti-acetylcholinestrate potential.

Keywords: AChE; IC50; Mitrephora poilanei; terpenes; β-caryophyllene.
