Product Description
Curcumin (Diferuloylmethane, CAS 458-37-7) is the principal bioactive polyphenolic monomer extracted and purified from the rhizome of Curcuma longa (Turmeric), a traditional medicinal and edible plant. As the core quality marker and most pharmacologically active ingredient of turmeric extract, Curcumin features a unique β-diketone structure, endowing it with excellent chemical activity and diverse biological functions. We supply high-purity Research Grade (98%) and Premium Functional Grade (99%) Curcumin crystalline powder, produced through standardized plant extraction, gradient resin separation and preparative HPLC fine purification. All products are strictly purified to remove curcumin analog impurities, plant fibers, heavy metals and solvent residues, ensuring single-component purity, stable batch activity and zero experimental interference. With outstanding anti-inflammatory, antioxidant, immunomodulatory, anti-tumor and metabolic regulatory effects, Curcumin has become a classic tool compound for modern pharmacological research and a mainstream high-value raw material for joint health, anti-aging and functional skincare product development.
Different from crude turmeric extracts containing Curcumin, Demethoxycurcumin and Bisdemethoxycurcumin, our pure Curcumin monomer possesses a definite molecular structure, clear pharmacological targets and controllable bioavailability, ensuring highly repeatable experimental results and standardized product efficacy. It exerts multi-pathway regulatory effects on human physiological and pathological processes. In anti-inflammatory regulation, Curcumin efficiently inhibits the activation of classic inflammatory signaling pathways including NF-κB, MAPK and COX-2, significantly reducing the expression of pro-inflammatory cytokines such as TNF-α, IL-6 and IL-1β. It relieves acute inflammation and chronic low-grade inflammatory responses, effectively improving joint inflammatory damage and systemic inflammatory aging.
In terms of antioxidant activity, the unique phenolic hydroxyl and β-diketone structure of Curcumin enables powerful free radical scavenging capacity. It efficiently eliminates intracellular reactive oxygen species, inhibits lipid peroxidation chain reactions, protects cell membrane and mitochondrial integrity, and reduces cumulative oxidative damage, thereby delaying cellular senescence and tissue aging. Beyond anti-inflammation and antioxidation, Curcumin exhibits excellent immunomodulatory effects by regulating immune cell proliferation and cytokine secretion, balancing immune responses and enhancing the body’s defense system. It also delivers metabolic regulation, liver protection, neuroprotection and anti-proliferative activities, covering multiple high-value research and application fields.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our high-purity Curcumin adopts standardized industrial production workflows including selective turmeric rhizome extraction, macroporous resin gradient impurity removal, preparative HPLC precision purification and multi-stage low-temperature recrystallization. The entire production process is carried out in a closed, dust-free and light-shielded low-temperature system to avoid structural oxidation and degradation of Curcumin active groups, fully retaining its original biological activity and pharmacological efficacy. The finished product presents uniform bright orange-yellow fine crystalline powder with stable texture, no agglomeration, no discoloration and no peculiar smell, completely free of miscellaneous impurities and harmful residues.
Every batch of Curcumin undergoes strict multi-dimensional quality verification, including HPLC high-precision purity detection, NMR structural identification, mass spectrometry molecular confirmation and cell-level biological activity evaluation. Ultra-low residual impurities and excellent batch-to-batch consistency guarantee stable pharmacological activity and reliable experimental data. With good solubility in common organic solvents and superior biocompatibility in cell culture and in vivo animal models, our Curcumin adapts to diverse scientific research scenarios and industrial formulation needs. We support long-term bulk stable supply, customized purity grades and professional vacuum light-proof packaging, providing cost-effective high-quality Curcumin raw materials for global research institutions, pharmaceutical laboratories, healthcare supplement manufacturers and cosmetic enterprises.
