ABSTRACT

INTRODUCTION: A treatment to the Alzheimer's disease consists inhibition of the acetylcholinesterase, which is responsible for the acetylcholine control in the synapses. METHODS: We have investigated the potential of inhibition of the acetylcholinesterase produced by hexane extracts of leaves, branches, and flowers from three Bauhinia specimens, which is based on the technique of thin layer chromatography and on identifying the organ of the plant that possesses larger concentration of inhibitors. RESULTS: Retention factor analysis shows values of 0.31aA, 0.31aA, and 0.46aB for flowers B. variegata, B. var. candida, and B. ungulata, respectively. CONCLUSIONS: The flower extract of B. ungulata is the most suitable for further studies on this inhibition.


INTRODUÇÃO: Um tratamento para a doença de Alzheimer consiste na inibição da acetilcolinesterase, responsável pelo controle de acetilcolina nas sinapses. MÉTODOS: Nós investigamos o potencial de inibição da acetilcolinesterase produzido por extratos hexânicos de folhas, ramos e flores de três espécimes de Bauhinia, realizado a partir da cromatografia em camada delgada e que órgão possui maior concentração de inibidores. RESULTADOS: Os fatores de retenção apresentaram 0,31aA, 0,31aA e 0,46aB para as flores de B. variegata, B. var. candida e B. ungulata respectivamente. CONCLUSÕES: O extrato de flores de B. ungulata é o mais satisfatório para futuros estudos desta inibição.
