Eighteen carotenoids as well as vitamin A and two forms of vitamin E (gamma- and alpha-tocopherol) have been separated from extracts of human plasma by high-performance liquid chromatography (HPLC) on reversed-phase and sillca-based nitrile-bonded columns. In the order of chromatographic elution on a C18 reversed-phase column, the carotenoids were identified as (3R,3'R,6'R)-beta, epsilon-carotene-3
在反相和基于Sillca的腈键色谱柱上,通过高效液相色谱(HPLC)从人血浆提取物中分离出了十八种类胡萝卜素以及维生素A和两种形式的维生素E(γ-和α-生育酚) 。按照在C18反相色谱柱上的色谱洗脱顺序,类胡萝卜素被鉴定为(3R,3'R,6'R)-β,ε-胡萝卜素-3,3'-二醇[(3R,3'R ,6'R)-叶黄素],(3R,3'R)-β,β-胡萝卜素-3,3'-二醇[(3R,3'R)-玉米黄质],5,6-二羟基-5,6 -dihydro-psi,psi-胡萝卜素,3-羟基-2',3'-二氢-β,ε-胡萝卜素-3-醇,3-羟基-β-胡萝卜素,psi,psi-胡萝卜素,7,8-二氢-psi,psi-胡萝卜素,beta,psi-胡萝卜素,7,8,7',8'-四氢psi,psi-胡萝卜素,beta,ε-胡萝卜素,beta,beta-胡萝卜素,7,8,11,12 ,7',8'-hexahydro-psi,psi-胡萝卜素和7
