Patent abstract
A simple and economic method of extracting free xanthophylls from plant material, particularly marigold petals and boxthorn berries, is described. The method relies upon salting out of aqueous components from a saponified oleoresin, which limits the use of organic solvents during the extraction and is also very economical.
