ABSTRACT
A target molecule affinity-ultrafiltration liquid chromatography-electrospray ionization tandem mass spectrometric (LC-ESI-MSn) method was established for rapid screening acetylcholinesterase (AChE) inhibitors from total alkaloids of fibraurea recisa Pierre.A total of 12 potential inhibitors were screened from Fibraurea recisa Pierre.and 6 compounds were identified including palmatine,berberine,jatrorrhizine,palmatrubine,7,8-dihydro-8-hydroxyberberine and groenlandicine.The AChE inhibitory activity of these 6 compounds was validated in vitro.Palmatine showed the strongest inhibitory activity for AChE,which was stronger than that of donepezil hydrochloride,demonstrating the potential of palmatine as anti-Alzheimer's drug.This method is simple,rapid,and accurate for directly screening active ingredients which can inhibit AChE from complex extract of traditional Chinese medicines.
