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

The inaja ( Maximiliana maripa ) is a palm from Arecaceae family. The inaja distribution occurs from Amazon to the west-central of South America. The inaja 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 inaja 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 inaja oil pulp was over 63.76%.
