RESUMO: "Comportamento e ensaios bioenzimáticos com Serjania erecta Radlk., sapindaceae, correlacionados com disfunções cognitivas." O objetivo deste estudo foi pesquisar o extrato bruto de Serjania erecta Radlk., Sapindaceae, e seus bioativos como preventivos ou inibidores de perda de memória em roedores, e outros fatores correlacionados com a síndrome de Alzheimer: atividade antioxidante e anticolinesterásicas, principalmente como planta adaptógena, baixa toxicidade e ação regulatória. A reversão do bloqueador colinérgico (escopolamina) no teste da esquiva passiva foi detectada pela latência mensurada em animais jovens e adultos. Apresentou baixa toxicidade, com efeito protetor na análise bioquímica (hipoglicemia/hipotrigliceridemia). Índices elevados (acima 83%) na atividade antioxidante foram observados. A inibição da AChE e BuChE foi perceptível nas frações cromatográficas, confirmando as ações via oral e diretamente no SNC.Unitermos: Serjania erecta, antioxidante, anticolinesterase, adaptógena, Alzheimer. ABSTRACT:The purpose of this study was to investigate the crude extract of Serjania erecta Radlk., Sapindaceae, and its bioactive agents as preventive or inhibitor of memory loss in rodents, as well as other factors correlated with Alzheimer's syndrome: antioxidant and anticholinesterase activity, mainly as plant adaptogen -low toxicity and regulation action. The blocking cholinergic reversion activity (scopolamine) in the test of the passive avoidance was detected by measuring latency in young and adult animals. It presented low toxicity, with protective effect as shown by biochemical analysis (hypoglycemic/ hypotriglyceridemic). Elevated levels (above 83%) of antioxidant activity were detected. AchE and BuChE inhibition were also detected in the chromatographic fractions, which were active both orally and directly on CNS (ICV).
