The Retionl Equivalent value and the composition of carotenoids in hen, quail and duck eggs were investigated by thin-layer chromatography. Total carotenoid contents per gram yolk were great in order of hen＞duck＞quail and retinol contents, quail＞duck＞hen. In Retinol Equivalent value, quail showed the highest level and hen showed the lowest level. In hen and quail, the contents of lutein and zeaxanthin of egg yolk were about 75% of their total carotenoid contents and they were about 60% in duck. In all cases, the sum of the concentration of lutein and zeaxantin accounted for more than 60% of the total carotenoid.
