Marigold

The progeny of Marigold goes back to the sixteenth century in Central America, specifically in Mexico.
The discovery of this plant in orange and red tons is granted to Portuguese people, who after spread it through Europe and Asian continent, where is nowadays well appreciated.
In spite of being present all over the world, if there are the specific conditions for its development, the biggest growing area of Mariagold is in China, followed by India and Peru.
The Marigold flower can be used for therapeutic purposes, for teas, essential oils for perfumery and dyeing, food additive and in more traditional areas is used with symbolical purposes and for ceremonies. For instance, the golden colour was considered as a symbol of honoured persons.
The flower reproduces exclusively by fruit – sed. As a rustic plant, doesn´t need special care, only soil, water and lots of sun. It is an invasive plant, especially in annual and perennial farming areas.
For conservation, the leaves and flowering parts should be dried in shade and in ventilated places, then kept in paper or fabric bags.

Biological characteristics

Xanthophylls (originally phylloxanthins) are yellow pigments that form one of two major divisions of the carotenoid group. The name is from Greek xanthos ("yellow") and phyllon ("leaf"), due to their formation of the yellow band seen in early chromatography of leaf pigments. Their molecular structure is similar to carotenes, which form the other major carotenoid group division, but xanthophyll contains oxygen atoms, while carotenes are purely hydrocarbons with no oxygen. Xanthophyll contains its oxygen either as hydroxyl groups and/or as pairs of hydrogen atoms that are substituted by oxygen atoms acting as a bridge (epoxide). For this reason, they are more polar than the purely hydrocarbon carotenes, and it is this difference that allows their separations from carotenes in many types of chromatography. Typically, carotenes are more orange in color than xanthophyll.

Lutein has a yellow tone and is a carotenoid found in high quantities in green leafy vegetables such as spinach, kale, peas, cauliflower, broccoli, in some fruits like orange, peach, papaya, and kiwi and egg yolk. It is one of the responsible for the pigmentation of those vegetables. It is used in medicine as an antioxidant, in the treatment of Age-Related Macular Degeneration. It can help or even prevent ocular degeneration and it is the main antioxidant that exists in ocular membranes.

Zeaxanthin is a substance that is responsible for the color of fishes, flowers, food and birds.
It is mainly found in yellow, orange and red vegetables such as nectarine, orange, papaya, broccoli Brussels sprouts, cabbage, cauliflower, peas, corn, rocket, eggs and so on.
Zeaxanthin is derived from secondary metabolism of many vegetables and can be grouped in carotenoid group which also includes carotenes. Indeed, Zeaxanthin is resulting from the carotenes oxidation.
