The extract of marigold comes from the medicinal plant marigold and is a natural extract. It is rich in lutein, zeaxanthin, carotenoids and flavonoids, which can protect eye health and has antioxidant properties. It is widely applied in various fields.

The extract of marigold flowers takes the form of powder, with a color ranging from yellow to orange. It has a faint fragrance of marigold flowers and is soluble in water, fats and organic solvents. It can be used in nutritional supplements, cosmetics and functional foods.

The main components of marigold extract

1. lutein (CAS No. 127-40-2),
The chemical formula of lutein is C₄₀H₅₆O₂. As a liposoluble compound, it has an orange-red color and is in powder form. Lutein can filter blue light and effectively prevent oxidation. It can protect the retina and is particularly beneficial for eye health.

2. zeaxanthin (CAS No. 144-68-3)
Zeaxanthin is usually an orange crystalline powder. Like lutein, it is also sensitive to light and oxygen and can enhance vision, protect the eyes from oxidation and damage caused by strong light.

3.Lutein esters (CAS No. 547-17-1)
Lutein esters, which are commonly found in products derived from marigolds, are used as dietary supplements and as a stable substance for product shelf life verification due to their excellent antioxidant properties and stability.

4.beta-carotene (CAS No. 7235-40-7)
The extract of marigold usually contains a small amount of beta-carotene. Its molecular formula is C₄₀H₅₆. It is in the form of a dark red to orange powder-like substance. Its functions are to enhance the human immune system, improve vision and skin function.

How to Extract Marigold ?

1. Processing of raw materials
The high-quality marigold flowers from the peak production season are selected. Through variety identification, maturity analysis, and contamination degree analysis, the petals with the highest quality, the best integrity, and the most compliant bioactive components are screened out to ensure that the quality of the raw materials meets the standards.

2. Preparation stage
This stage involves cleaning and drying the marigold flowers to reduce their moisture content and allow the carotenoids to be fully retained.

3. Concentration and purification stage
Under controlled stable and pressurized conditions, the dried marigold flowers are subjected to concentration extraction and multiple purification operations to remove waxes, chlorophyll, and other unnecessary components.

4. Standardization processing stage
The data of the marigold extract are tested to ensure they meet the quality standards, and to guarantee that the bioactive components are compliant, such as ensuring that the lutein content is between 5% and 80%. 5.Stabilization

The standardized extract undergoes a critical stabilization process to protect sensitive carotenoids from oxidation. This typically involves the addition of natural antioxidants such as mixed tocopherols, ascorbic acid, or rosemary extract.

5. Final Stage
The final stages involve converting the stabilized extract into powder form through spray-drying or drum-drying operations. During this stage, strict control of the drying parameters is necessary to maintain the stability of carotenoids and to achieve the desired particle characteristics.

Benefits of marigold extract

1.Eye health and improved vision
The extract of marigold can improve the condition of the macula in the eyes and enhance visual functions. According to the research data from “Nutrition” (2022), after continuous use for 8 to 12 weeks, visual functions will be significantly improved.

2. Accelerate wound healing
The research published in the Journal of Ethnopharmacology (2022) showed that the extract of marigold could promote wound healing, enhance the function of regenerative tissues, and possess antibacterial properties.

3. Improve digestive system function
Clinical studies in BMC Complementary Medicine (2023) have shown that marigold extract can reduce intestinal inflammatory markers and is helpful for improving the digestive system.

4. Enhance immune capacity
Recent research in Frontiers in Immunology (2022) revealed that marigold extract can balance the human immune capacity, enhance cell activity, regulate immune system function, and have potential effects on seasonal diseases and immune recovery.
