A method is described for the qualitative and quantitative determination of configurational isomers of zeaxanthin (= 3,3' -dihydroxy-P, p -carotene) and lutein (= 3 3 -dihydroxya-carotene). It is based on the reaction of these zeaxanthin and lutein isomers with (S)-(+)-e-(l -naphthyl) ethyl isocyana
## Abstract Circular dichroism (CD) spectroscopy was used to distinguish between the isomeric (all‐__E__)‐configured 3′‐epilutein (**2**) and 6′‐epilutein (**8**) to establish the absolute configuration of epilutein samples of different (natural and semisynthetic) origin, including samples of **2**
