Marigold Extract Lutein manufacturers
Lutein, like beta carotene as a member of cartenoids, is one of more than 600 kinds of natural carotenoids that have been found so far. It belongs to photosynthetic pigment. It is lipophilic and usually insoluble in water. In flowers, it exists in free form in green vegetables and some algae; the esterified lutein in plants can be saponified to prepare free lutein.
