Objective: To assess the effect of different polarity extracts from Psychotria rubra on learning and memory abilities of mice. Method: P. rubra was extracted by 95% ethanol
and then was extracted by petroleum ether
ethyl acetate and butanol respectively. The dose of different polar extracts and piracetam was 200
120 mg·kg-1
respectively. Effect of different polarity extracts from P. rubra on learning and memory abilities was tested in the mice model caused by chlorpromazine hydrochloride
sodium nitrite
ethanol and scopolamine
respectively
and screened the active part of P. rubra. Result: Extracts from P. rubra could prolonged latency and decreased error frequency of mice. Conclusion: The ethyl acetate extracts and the water extracts of P. rubra can improve the learning and memory abilities and the ethyl acetate extract may be an active part.
