La cromatografía líquida de alta eficacia en la separación de triglicéridos de grasas animales complejas

Abstract

[ES] Los triglicéridos son una de las fracciones lipídicas más abundante y al mismo tiempo más compleja de la naturaleza. Por esta razón, es esencial la determinación de sus especies moleculares, así como conocer la posición estereoespecífica en que se sitúan los ácidos grasos que los componen, para caracterizar las grasas animales y los aceites vegetales. La técnica más comúnmente empleada con este fin es la cromatografía líquida de alta eficacia (HPLC), en general utilizando columnas de fase reversa. En el presente artículo se describen las condiciones operativas que actualmente se emplean para alcanzar la óptima resolución de picos cromatográficos de triglicéridos, así como la situación actual del conocimiento en materia de separación de especies moleculares de mezclas de triglicéridos complejas, tales como la grasa láctea, el aceite de pescado y la grasa hepática, que son de importancia en el sector industrial y en la nutrición humana.

[EN] Triglycerides are at the same time, one of the most abundant and complex lipid fraction in the nature. For this reason, it is esential to determine their molecular species composition, as well as to know the stereospecific position in which the fatty acids are located, in order to characterize animal fats and vegetable oils. The most commonly employed technique for this objective is high-performance liquid chromatography, in general using reversed phase columns. In the present article we describe the operative conditions employed nowadays in order to achieve the optimum resolution for the triglyceride chromatographic peaks, and also the present situation of the knowledge in the separation of the molecular species of complex mixtures of triglycerides, such as milk fat, fish oil and hepatic fat, which are of importance in the industrial sector and human nutrition.
