Recently, Xi’an Natural Field Bio-Technique Co.,Ltd.’s Technicist Found a secret of the Lutein’s ingredient that we have meso-zeaxanthin in the lutein of Marigold Flower Extract after checked some documents about Zeaxanthin.
From the effect, meso-zeaxanthin has main effect on protecting eyes. The mesco-zeaxanthin is widely used as eyes health supplements.
There are four stereoisomers in the Zeaxanthin. Namely

1. 3R, 3'R-zeaxanthin, ------Zeaxanthin
2. 3S, 3'S-zeaxanthin, -------/
3. 3R, 3'S-zeaxanthin,-------meso-zeaxanthin
4. 3S, 3'R-zeaxanthin.------meso-zeaxanthin
However, the zeaxanthin molecular structure is a Chiral Isomer, 3R, 3'S- and 3S, 3'R- these two stereoisomers are actually the same.
Thus, zeaxanthin actually has only three stereoisomers, of which 3R, 3'S-zeaxanthin and 3S, 3'R-zeaxanthin are known as meso-zeaxanthin, and naturally occurring zeaxanthin predominantly Is 3R, 3'R-zeaxanthin.
Lutein 20%, it has 1% 3R, 3'R-zeaxanthin,
Lutein 40%, has 2% 3R, 3'R-zeaxanthin,
Lutein 60% has 3% 3R, 3'R-zeaxanthin.
