ABSTRACT: 

Acetylcholinesterase (AChE) inhibition is considered as a promising strategy
for the treatment of neurological disorders. The aim of this research was to determine the
chemical composition of the aerial parts of Crotalaria retusa by gas chromatography coupled
to mass spectrometry (GC-MS), and evaluate their anticholinesterase and cytotoxic potential
against Artemia salina. The main compounds found were trans-hex-2-enal (66.67%) in
fresh leaves; in dry leaves benzene acetaldehyde (23.90%), and in fresh flowers 3-ethyl4-methyl-pent-3-en-2-one (42.80%). The volatile constituents of fresh leaves, hexane
and ethanolic extracts, decoction and dichloromethane fraction showed inhibition against
AChE. The extracts were found to be nontoxic against Artemia salina, which increases the
perspectives of study of the species about new biological activities.

RESUMO

Composição química e avaliação anticolinesterase de partes aéreas de Crotalaria
retusa. A inibição da acetilcolinesterase (AChE) é considerada uma estratégia promissora
para o tratamento de distúrbios neurológicos. O objetivo desta pesquisa foi determinar
a composição química das partes aéreas da Crotalaria retusa por cromatografia gasosa
acoplada à espectrometria de massas (CG-EM), e avaliar seu potencial citotóxico e
atividade anticolinesterase. Os principais compostos identificados foram trans-hex-2-
enal (66,67%) nas folhas frescas; fenilacetaldeído (23,90%) nas folhas secas, e nas
flores frescas 3-etil-4-metilpent-3-en-2-ona (42,80%). Os constituintes voláteis das folhas
frescas, hexano e extratos etanólicos, decocção e fração diclorometano apresentaram
inibição da AChE. Os extratos foram encontrados não tóxicos contra Artemia salina, o
que aumenta as perspectivas de estudo da espécie sobre novas atividades biológicas.
