Chemical composition of fixed oils from the seeds of Azadirachta indica

Understanding the chemistry of oils and fats as well as their extraction methods is of fundamental importance to human beings taking into account the great diversity of products that can be generated from them as well as their use for pharmacological industrial and nutritional purposes. The aim of this study was to characterize the chemical composition of the fixed oil of Azadirachta indica (Nim) seeds in terms of its fatty acids using different extraction processes. This characterization was determined by Gas Chromatography Coupled to Mass Spectrometry (GC-MS) through its methyl esters obtained by the transesterification and saponification processes separately. The study made it possible to characterize the oil from Azadirachta indica (Nim) seeds using the methodologies initially proposed. In addition the results were logical and solid confirming methyl octadec-9-enoate as the main product in all the chromatograms.
