The invention discloses a method for preparing
lycium barbarum
lutein by HSCCC (high-speed
countercurrent chromatography) separation. The method mainly comprises the following steps:
grinding and extracting
lycium barbarum
berry, concentrating extract, saponifying, eluting and dissolving, and carrying out HSCCC separation to obtain a
lycium barbarum
lutein solution; concentrating, and freeze-
drying to obtain a
lutein pure product of which the purity is over 90.6 percent by means of
HPLC analysis and detection. According to the method, a
methanol and
tetrahydrofuran composite
solvent is adopted for ultrasonic extraction, and a
saponification technology is combined and synergized with HSCCC, so that the problem that main carotinoid lutein and zeaxanthine in lycium barbarum belong to isomers and are difficult to separate can be successfully solved; autumn
berry of lycium barbarum is utilized as a
raw material, so that the production cost is greatly reduced, effective separation of lutein and zeaxanthine can be successfully realized by repeatedly regulating the
solvent proportion in the counter-current
chromatography separating and purifying phase, a high-purity lutein
monomer can be obtained, and a new thought is provided to implementation of separating and purifying lutein from lycium barbarum and implementation of industrial production.
