Characterisation of Moringa oleifera's oils from different extraction methods

Abstract

Moringa oleífera is a plant that is used as raw material in various industries, including those related to the field of chemistry such as food, pharmaceuticals and cosmetics. One of the usable parts of the tree is the seed because the content between 30 and 45% oil. They enhance its therapeutic use in the treatment of more than 300 diseases. In this research the oil extracted from the seeds of Moringa oleífera varieties of Cuban origin Supergenious, Plain and Nicaragua is characterized from solid-liquid extraction with hexane and ethanol as solvents and by the method of mechanical pressing of the species Nicaragua . Through a design of experiment 2K solute-solvent variable ratio, extraction time were analyzed, and the grain size selected runs with values greater percentage of oil extracted. Oils corresponding to the selection were characterized physic-chemical and phytochemically and were compared with varieties from different regions reported in the literature. It was shown that the pressing method is efficient, economical and has no influence on the product properties obtained.
