The adsorption and partition properties of several fatty acid esters of capsanthin, capsorubin, beta-cryptoxanthin, lutein, violaxanthin and beta-citraurin isolated from fruits were studied by normal-phase (silica) and reversed-phase (octadecylsilane) liquid chromatography using Sudan 1 as internal standard. The separation on
