| Authors: | Max Vecchi Robert K Müller |
| Abstract: | A method is described for the qualitative and quantitative determination of configurational isomers of astaxanthin. It is based on the esterification of astaxanthin with (—)-camphanic acid chloride and analysis of the corresponding diesters by HPLC. |
