Lutein Esters

English Name: Lutein Esters

Chemical name: lutein dipalmitate (CAS Registration No.: 547-17-1)

Molecular formula: C72H116O4

Molecular weight: 1045.69

EINECS No.: 208-916-4

Overview: at room temperature, lutein ester with high purity (content 60% - 95%) is golden yellow and orange red powder. It is easily soluble in chloroform, dichloromethane, carbon dichloride and other chlorinated hydrocarbons, and soluble in n-hexane, acetone and ethyl acetate 、 Ethanol and other solvents are more stable than lutein. Lutein ester is greatly damaged only under the factors of high temperature, strong acid, iron ion and oxygen.

Usage: lutein ester is the main component of human retina and macula. It has strong antioxidant capacity, prevents oxidative damage of free radicals to the eyes, improves eye microcirculation, prevents senile cataract, protects the retina and prevents optic nerve atrophy. Lutein ester must be taken from food.

Properties

Duxinju is a plant of the genus duxinju in Compositae. In addition to ornamental, duxinju can also be used as medicine. In the aspect of traditional Chinese medicine, the whole herb with flowers of duxinju is used as medicine to treat liver and kidney yin deficiency, dizziness, weak waist and knee, early white beard, rheumatoid arthritis and other diseases. Lutein ester is an important carotenoid fatty acid ester with dark reddish brown fine particles. Most lutein esters existing in nature can be divided into trans lutein esters and CIS lutein esters, which are basically all trans molecular configurations. All trans lutein esters can be divided into lutein monoester and lutein diester. It widely exists in Wanshou chrysanthemum, pumpkin, cabbage, shouzao and other plants. Among them, the content of Marigold is the most abundant, as high as 30% to 40%. In marigold and other plants, lutein generally exists in the form of ester combined with fatty acids (such as lauric acid, palmitic acid, etc.).
