WHAT IS CURCUMIN USED TO TREAT?

1、How is curcumin extracted from turmeric?

Curcumin is a diketone phenolic pigment extracted from the roots of turmeric of the genus Curcuma, which is an orange-yellow crystalline powder with a slightly bitter taste. Over the years, heavy metal residues have not been easily separated and removed. In the separation and purification preparation method of high-purity curcumin, there is still a lack of focus on the problem of heavy metal residues. U.S. Patent No. 5,679,864 discloses the extraction of curcumin with a suitable organic solvent, the dissolution of the extract in an aqueous polar solvent, the addition of an excess of a non-polar solvent, the addition of a precipitate to give a precipitate, and the addition of the precipitate to acetone, ethanol or a mixture thereof. It is recrystallized.
