We have two kinds of Marigold Flower Extract, lutein ester and lutein free which are all come from marigold flower.Lutein ester is directly separated from marigold flower by recrystallization. And lutein free is obtained by saponification of lutein oleoresin.

   There are many differences between these two kinds of products. For example, lutein ester is an oil soluble material, but lutein itself is not. Lutein ester is a dark-red powder, and lutein is a yellow-orange powder.We show you 2 HPLC spectrums contrast the difference between them.

Marigold flowers is originally planted in Mexico, but currently in Heilongjiang, Jilin, inner Mongolia, Shaanxi, Yunnan province and other places of China also have large-scale cultivation .

    As known from the above form, lutein is present in plants as fatty-acid esters, with one or two fatty acids bound to the two hydroxyl-groups. For this reason, saponification (de-esterfication) of lutein esters to yield free lutein may yield lutein in any ratio from 1:1 to 1:2 molar ratios with the saponifying fatty acid. So there are two kinds of products form extract from marigold flower, lutein and lutein ester.
