Original Research


Skimmianine (1), a newly discovered strong acetylcholinesterase (AChE) inhibitor, along with nine weakly or no active compounds, toddalolactone (2), dictamnine (3), γ-fagarine (4), magnolone (5), (−)-(S)-edulinine (6), zanthodioline (7), edulitine (8), 5,6,7-trimethoxycoumarin (9), and haplopine (10) have been isolated from Zanthoxylum nitidum (Z. nitidum). Skimmianine (1) inhibited 50% of AChE activity at the concentrations of 8.6 ± 0.7 μg/ml when the IC50 value of Physostigmine as a standard was 0.013 ± 0.002 μg/ml. Antiacetylcholinesterase activity of skimmianine (1) was also supported by TLC bioautographic assay. The structure activity relationship on the anti-acetylcholinesterase activity of the quinoline moiety is also discussed in this article.
