摘要：

The yellow petals of rape (Brassica napus) were extracted with hexane/acetone/MeOH/toluene (10: 7:6:7), EtOAc/hexane/acetone (6:1:1), and EtOAc/Et2O (1:1), and subsequently the saponified extract was submitted to a step gradient on an Al2O3 column. From the most polar fraction, two (Z)-isomers of lutein have been isolated by reversed-phase HPLC. On the basis of UV-vis, CD, 1D and 2D 400 MHz H-1-NMR, and mass spectra they were identified as (9Z,9'Z,3R,3'R,6'R)-lutein and (13'Z,3R,3'R,6'R)-lutein.
