Title (EN) METHOD OF RECOVERING XANTHOPHYLL
(FR) PROCEDE DE RECUPERATION DE XANTHOPHYLLE
(JA) キサントフィルの回収方法
Abstract: front page image
(EN)A method of recovering xanthophylls, comprising the adsorption step of bringing a sample containing xanthophylls into contact with a hydrophilic resin so that the resin adsorbs the xanthophylls, and the desorption step of leaching the xanthophylls adsorbed on the resin by means of a polar solvent. Preferable, the washing step of washing the resin is interposed between the adsorption step and the desorption step. A hydrophilic acrylate and/or methacrylate resin is preferably used as the resin.
(FR)L’invention concerne un procédé de récupération de xanthophylles, comprenant l’étape d’adsorption consistant à mettre en contact un échantillon contenant des xanthophylles et une résine hydrophile de sorte que la résine adsorbe les xanthophylles, ainsi que l’étape de désorption consistant à lixivier les xanthophylles adsorbées sur la résine au moyen d’un solvant polaire. De préférence, l’étape de lavage de la résine est intercalée entre les étapes d’adsorption et de désorption. De préférence, la résine est un acrylate hydrophile et/ou une résine méthacrylate.
(JA)本発明は、キサントフィル類の回収方法を提供し、該方法は、キサントフィル類を含有する試料と親水性樹脂とを接触させ、該キサントフィル類を該樹脂に吸着させる吸着工程;および該樹脂に吸着したキサントフィル類を極性溶媒で溶出させる脱着工程;を含む。好ましくは、吸着工程と脱着工程との間に樹脂を洗浄する洗浄工程を含む。樹脂としては親水性のアクリル酸系および/またはメタクリル酸系の樹脂が好ましく用いられる。
