Congress Abstract

We isolated 2,3-dihydroxy-4-methoxyacetophenone from Cynenchum paniculatum which we have previously reported as having an neuroprotective effect. The objective of this study was to investigate the cognitive-enhancing effect of 2,3-dihydroxy-4-methoxyacetophenone on scopolamine-induced amnesia. SCOP (1 mg/kg, i.p.) induced a learning and memory deficit measured both during and after training 2,3-dihydroxy-4-methoxyacetophenone was orally administered to amnesic mice induced by scopolamine and the mice were then evaluated using the Morris water maze test. The results showed that 2,3-dihydroxy-4-methoxyacetophenone ameliorated scopolamine- induced amnesia based on the Morris water maze test. We suggest that 2,3-dihydroxy-4-methoxyacetophenone improve cognitive function and may be helpful for the treatment of Alzheimer's disease.
