Inhibition of Acetylcholinesterase and Fatty Acid Composition in Theobroma grandiflorum Seeds

Theobroma grandiflorum is an important fruit tree from Sterculiaceae family, native to the Brazilian Amazon, known in the region as cupuaçu. The seeds have a high fat content (24%) with characteristics that resemble those of cocoa (Theobroma cacao) butter with potential applications in the cosmetic, pharmaceutical and food industries. The main objective of this work was to explore the seed fats from T. grandiflorum that were analyzed for fatty acid composition by Gas Chromatography with Flame Ionization Detector (GC-FID) and to analyze their activity for acetylcholinesterase inhibition. Chromatographic analysis provided detection of nine fatty acids. The major fatty acids found in the species were oleic (40.0%), stearic (32.7%), arachidic (10.4%) and palmitic (8.0%). The acetylcholinesterase inhibition by fats from seeds was over 40.48%. DOI: http://dx.doi.org/10.17807/orbital.v0i0.89

Oil in Inajá Pulp (Maximiliana maripa): Fatty Acid Profile and Anti-acetylcholinesterase Activity

The inajá (Maximiliana maripa) is a palm from Arecaceae family. The inajá distribution occurs from Amazon to the west-central of South America. The inajá has edible parts: the palm heart and oils obtained from pulp and seed. The aims of this study were to verify the fatty acid profile from pulp oil by GC-FID and analyzing acetylcholinesterase inhibition by inajá pulp oil. Chromatographic analysis provided eleven fatty acids. The major unsaturated fatty acids are oleic (22.32%), linoleic (4.72%) and linolenic acids (3.95%). The major saturated fatty acids are palmitic (20.76%), myristic (20.48%) and lauric acids (17.42%). The acetylcholinesterase inhibition by inajá oil pulp was over 63.76%. DOI: http://dx.doi.org/10.17807/orbital.v7i4.76
