High-Purity Curcumin 90/95/98/99% Turmeric Extract là gì? Ứng dụng, liều dùng, sản phẩm thay thế & thông số

Curcumin (CAS 458–37–7) is a natural polyphenolic compound extracted from the rhizome of turmeric (Curcuma longa L.). It is the principal curcuminoid and the most bioactive component of turmeric. Chemically named (E,E)-1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione, it has the molecular formula C21H20O6 and a molecular weight of 368.38. Curcumin is the core component of curcuminoids; natural turmeric extract typically contains curcumin (approximately 70%-80%), demethoxycurcumin (approximately 16%-20%), and bisdemethoxycurcumin (approximately 2%-6%). Turmeric has been used as an ancient spice and medicine in India for over 6,000 years and is the primary coloring component of curry powder. Curcumin is the natural source of turmeric‘s bright yellow color and is the material basis for its multiple physiological activities. High-purity curcumin (>98%) refers to a high-value-added product where the purity of the curcumin monomer has been elevated to above 98% through advanced extraction and purification processes. It represents the highest grade among natural curcuminoid ingredients and is primarily used in premium dietary supplements, pharmaceutical preparations, and high-end cosmetics. The unique value of high-purity curcumin lies in its higher purity, fewer impurities, stronger activity, and more precise efficacy. Compared to regular turmeric extracts, high-purity curcumin allows for more accurate quantification of active components, meeting the demand of modern health foods and pharmaceutical products for standardized, high-activity raw materials.

Curcumin has a wide range of pharmacological activities and is one of the most deeply researched natural polyphenolic compounds.

The molecular structure of curcumin contains multiple phenolic hydroxyl groups and a β-diketone structure, enabling it to effectively scavenge free radicals, inhibit lipid peroxidation, and significantly increase the activity of the body‘s antioxidant enzymes, playing a potential preventive and therapeutic role in various oxidative stress-related diseases.
