Introduction for Lutein and zeaxanthin

Lutein and zeaxanthin are a very important class of carotenoids with superior physiological functions. In nature, lutein is often present in combination with jade yellow, especially in marigold. The ratio of lutein to jute is about 93:7. Lutein and zeaxanthin together constitute retinal pigment. They protect retinal cells by filtering and absorbing high-energy destructive blue light. In addition, they are good antioxidants that block free radicals, quench singlet oxygen and capture reactive oxygen free radicals, protecting the retina from Free radical damage.


New application

With the deepening of the research on the physiological functions of Lutein and zeaxanthin, more and more people have been working on the extraction, purification and processing of lutein. Due to the asymmetry of the molecular structure of Lutein and zeaxanthin, chemical synthesis of Lutein and zeaxanthin is difficult, so lutein is generally extracted from plants containing higher Lutein and zeaxanthin, especially marigold. In the extraction of carotenoids, the solvents commonly used in Shaanxi Huatai bio-fine Chemical Co.,Ltd is petroleum ether, n-hexane, acetone, ethanol, ethyl acetate and other solvents.Lutein and zeaxanthin.jpg


The results showed that the solubility of Lutein and zeaxanthin in n-hexane, petroleum ether, ethanol, acetone and ethyl acetate increased with increasing temperature, indicating that Lutein and zeaxanthin have positive solubility. Among the five solvents, Lutein and zeaxanthin had the highest solubility in ethyl acetate at the same temperature, followed by acetone and ethanol, and n-hexane and petroleum ether were relatively close and minimal.
