Inibição de acetilcolinesterase a partir de extratos de Bauhinia variegata L., Bauhinia variegata var. candida (Aiton) Buch.-Ham., e Bauhinia ungulata L

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.
