✦ Synopsis

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 isocyanate to afford diastereomeric dicarbamates, which are analyzed by HPLC.

## Abstract The temperature dependent CD. spectra of (3__S__, 3′__R__)‐ and (3__S__, 3′__S__)‐adonixanthin are compared with those of (3__R__, 3′__R__)‐zeaxanthin (**1**) and (3__S__, 3′__S__)‐astaxanthin (**2**). The room temperature spectra of **1** and **2** are quite similar. On cooling to −180
