Chemical composition and acetylcholinesterase inhibitory activity of essential oil from rhizomes of Distichochlamys benenica

Abstract

Twenty-seven constituents were identified by using GC/MS, representing 99.57% of the rhizome oil of Distichochlamys benenica. The major constituents of the essential oil are 1,8-cineole (54.39%), β-pinene (7.50%), (E)-citral (7.26%), and (Z)-citral (6.79%). The rhizome essential oil has anti-acetylcholinesterase activity with an IC50 value of 136.63 ± 2.70 mg/mL.
