- W2389370892 abstract "Objective:To extracte and isolate acetylcholinesterase inhibitory activity of compound from Gentiana purdomii.Methods:Gentiana purdomii was extracted by ethanol and treated with hydrochloric acid and base,and then extracted by Chloroform to obtain extracts,and the extract was gained and chromatography was separated step by step.Their chemical structures were identified by 1H-NMR and 13C-NMR spectra.The detection limit was extracted by TLC bioautographic assay.Results and Conclusion:Two fractions were obtained by the silica-gel column chromatography.Two compounds were confirmed to be secostrychnosin(1) and(4R,4aS)-4-vinyl-4,4a,5,6-te-trahydro-3H-pyranopyran-1-one(2).The compounds 1 and 2 of minimal inhibitive dose are 0.5 μg and 1.0 μg." @default.
