发明名称 Method for production of rare carotenoids from commercially available lutein
摘要 Disclosed are processes for conversion of (3R,3'R,6'R)-lutein to (3R,6'R)-alpha-cryptoxanthin, (3R)-beta-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)-alpha-cryptoxanthin in excellent yields.
