Calendula (marigold) is a wild flower plant rich in carotenoids and yellow pigments. It has been successfully introduced and planted in large areas in northeast, north and northwest China. Calendula is a green renewable resource that has important economic value and can be developed and utilized. It is rich in extremely precious yellow pigment components and antioxidant functional factors-lutein esters and lutein (Lutein) carotenoids, and Quercetin marigold flavonoids can be used as important pharmaceutical intermediates (eyesight, anti-myopia, prevention of age-related macular disease) and functional natural food additives (colorants and antioxidants).
The expert group believes that the project uses modern advanced extraction and separation technology to deeply research and develop the advanced preparation technology and core technology of green natural colorants, functional food additives and pharmaceutical intermediates of Gansu Calendula yellow pigment and lutein, Combined with the industrial foundation of planting and processing of characteristic plant resources of Calendula officinalis in Gansu, researches on extraction, refining, structural characterization, and stability of high-purity yellow pigment and lutein were carried out to solve the problem of poor water solubility and no It is stable and easy to be oxidized. It realizes simple, efficient and rapid separation and purification of yellow pigment and lutein, and obtains high-purity yellow pigment and lutein products. Developed Calendula Lutein Fuwei soft capsule product and conducted a pilot test.
The research results have broken through the technical barriers for deep processing of marigolds, solved the key technologies for the preparation of marigold yellow pigment and lutein, mastered the core technical parameters, and the overall achievements have reached the international advanced level. The research results are helpful to promote the healthy and stable development of Gansu Calendula planting industry, extend the industrial chain of characteristic resource processing and utilization, and develop green industries, which is of great significance to the adjustment of the agricultural industry structure in the western region and the sustainable development of the regional economy.
