Abstract: The chemical constitutes of the EtOH extract of Pteris vittata from Jiangxi Province were studied.Severn compounds were isolated by repeated gel column chromatography.On the basis of spectral data,their structures were characterized as apigenin (1),apigenin-7-O-β-D-glucopyranoside (2),luteolin (3),luteolin-7-O-β-D-glucopyranoside (4),kaempferol-3-O-β-D-glucopyranoside (5), β-sitosterol (6).All Compounds were isolated from this species for the first time.Compound 5 showed a certain acetylcholinesterase inhibitory activity.

Key words: Pteris vittata, chemical constituents, bioactivity
