摘要：

Systematic chromatography resulted in the isolation of 4 geometric isomers as products of iodine-catalyzed isomerization of lutein. 13C NMR spectral analysis established their streochemistry as mono-cis luteins with a cis-configured double bond at C-9, C-9'', C-13 and C-13'', respectively. 13C NMR also provided unambiguous stereochemical assignment for the previously isolated 4 mono-cis capsanthins.
