Identificación de pigmentos en plantas superiores por cromatografía líquida de alta eficacia en fase reserva

Abstract

[ES] En el presente trabajo se describe un método cromatográfico que ha servido para la separación, con buenos resultados, de pigmentos cloroplásticos de espinaca, remolacha azucarera y naranjo. El equipo instrumental utilizado está constituído por una bomba de alta presión, una columna de fase reversa, un módulo de compresión radial y un espectrofotómetro registrador. Este tipo de columnas permite la separación simultánea de clorofilas y carotenoides en un cierto intervalo de tiempo. Esta metodología no produce degradación de pigmentos. El coeficiente de variación de los tiempos de retención de cada pigmento es menor del 0,9%, lo que permite la identificación de los mismos con gran precisión.

[EN] A chromatographic methods was developed for the separation of chloroplast pigments from spinach, sugar-beet and orange tree. The apparatus consists in a high-presure pumping, a reversed-phase column, a radial compression module and a recording spectrophotometrer. This kind of column allows the simultaneous separation of chlorophylls and carotenoids with a short analysis time. This separation mechanism does not cause pigment degradation products. The coefficient of variation of the individual retention times for each pigment is better than 0.9% wich facilitates the pigment identifications.
