Abstract

Taraxacum platycarpum H. Dahl. (Compositae) has been used as an anti-inflammatory or anti-cancer agent in the clinic. Although its antidepressant effect has been reported, however, its cognitive function is not investigated until yet. In the present study, we investigated whether the water extract of T. platycarpum (WETP) could improve cognitive function in cholinergic blockade-induced amnesia mouse model using the passive avoidance or Y-maze task. WETP (12.5, 25 or 50 mg/kg) significantly ameliorated the scopolamine-induced cognitive impairment both in the passive avoidance test and the Y-maze test. In addition, WETP significantly inhibited acetylcholinesterase (AChE) activity measured by an ex vivo study using the mouse whole brain. These results suggest that WETP alleviates the cognitive dysfunction caused by the cholinergic blockade, in part, via AChE inhibition, and that it may be a useful for treating cognitive dysfunction.
