This invention provides a green and efficient method for extracting and purifying lutein from marigolds, belonging to the field of extraction, separation, and purification of fat-soluble active ingredients. The invention involves pulverizing fresh or dried marigold flowers and then using an aqueous solution of dodecyl dimethyl betaine for green extraction and purification of lutein. Based on the characteristic that dodecyl dimethyl betaine forms supramolecular interfacial charges with lutein in aqueous solution, and utilizing the fact that low temperatures significantly affect the stability and morphology of micelles, the critical micelle concentration of dodecyl dimethyl betaine decreases with decreasing temperature, and the solubility of lutein in the mixed system further decreases, lutein is precipitated and aggregated. The lutein-bound state, such as lutein esters, is then saponified using an alcohol-alkali method, followed by ethanol recrystallization to obtain high-purity lutein. This new green and efficient method for extracting and purifying lutein from marigolds provides high extraction rates and high purity. The method not only improves the extraction efficiency of lutein but also has significant implications for the safe industrial production of lutein.

This invention discloses a method for extracting and purifying lutein extract based on a composite solvent system, specifically relating to the field of natural product separation and extraction. The method involves mixing a crude extract containing lutein esters from marigold with a first composite solvent system. This allows lutein esters, oils, and resinous impurities in the crude extract to enter the liquid phase. Waxes are then precipitated by lowering the system temperature, resulting in a dispersion system containing the precipitated waxes. The first composite solvent system consists of a first organic solvent and a second organic solvent. By first introducing lutein esters, oils, and resinous impurities into the liquid phase in the first composite solvent system, then allowing the waxes to precipitate and separate, and subsequently transferring the lutein esters to a lutein ester-enriched phase, lutein can be separated from major accompanying impurities before entering the saponification and purification processes. This relatively reduces the burden on subsequent processes and alleviates issues such as slow stratification, increased entrainment, and batch fluctuations.

This invention discloses a catalyst composition, a method for preparing zeaxanthin ester, and the zeaxanthin ester itself. The catalyst composition, comprising an alkaline catalyst and a carbonyl iron catalyst, is used to isomerize lutein ester into zeaxanthin ester. Under alkaline conditions, the catalyst composition of this invention allows the carbonyl iron catalyst to complex with the double bond electron cloud of the 4', 5' carbon atom on the terminal benzene ring of the lutein ester molecule, significantly reducing the energy required for the terminal carbon to capture protons. This facilitates the migration of protons from one negative carbon ion site (6' carbon atom) to another site (4' carbon atom), accelerating the transfer of the double bond position. This reduces the activation energy, decreases the amount of alkaline catalyst required, shortens the reaction time, lowers the reaction temperature, and improves the conversion rate and yield of lutein ester.
