The Research of Reaction Conditions of High-purity Lutein in the Extraction of Tageles Erecta Linn

Lutein is a sort of natural food coloring matter.Through the research, we found the lutein has the efficiency of eye health, skin care and anti-cancer.Furthermore it is the composition of feedstuff and food additives applied its stain ability, so lutein has broad market exploitability.The primary purpose of this experiment was study the conditions of saponification in the course of purification with Lutein.Self-made marigold extraction for raw material, View the effication of lutein content with saponification agent, quantity added to base, concentration added to base, temperature of saponification and time of saponification, finally defined the optimal conditions of saponification and screen out the better conditions of leaching and re-crystallization.
