Disclosed are processes for conversion of (3R,3′R,6′R)-lutein to (3R,6′R)-α-cryptoxanthin, (3R)-β-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)-α-cryptoxanthin in excellent yields.
