Document Type and Number:
WIPO Patent Application WO2002010128
Kind Code:
A3
Abstract:
Disclosed are processes for conversion of (3R,3'R,6'R)-lutein to (3R,6'R)- -cryptoxanthin,(3R)- -cryptoxanthin, anhydroluteins I, II, and III (dehydration products of lutein), and a method for separating and purifying the individual carotenoids including the unreacted (3R,3'R)-zeaxanthin. The invention also includes two methods that transform (3R,3'R,6'R)-lutein into (3R,6'R)- -cryptoxanthin in excellent yields.
