Product Description
Our Alpinetin powder is a high-purity natural flavanone active ingredient, available in 98% and 99% HPLC grades. Alpinetin (CAS 1090-65-9), commonly known as is a signature bioactive flavonoid isolated from the traditional Chinese medicinal herb Alpinia katsumadai Hayata. Possessing a unique 5-methoxy-7-hydroxyflavanone structure, Alpinetin delivers stable molecular activity and multi-dimensional pharmacological properties, standing out among natural plant flavonoids for its excellent anti-inflammatory, antibacterial, antioxidant and anti-tumor performance. It is widely used in soothing skincare formulas, antibacterial functional products, anti-oxidation health supplements and biomedical pharmacological research. As a professional bulk Alpinetin supplier, we provide high-purity, stable-batch and fully compliant products for global industrial and scientific research clients.
Alpinetin belongs to the flavanone subclass of flavonoids, with superior biological stability compared to many common plant active ingredients. Its core functional mechanism focuses on activating the PPAR-γ signaling pathway, effectively inhibiting NF-κB inflammatory cascade response, and blocking the release of multiple pro-inflammatory cytokines. This enables Alpinetin to efficiently relieve acute and chronic inflammation without causing irritation or side effects. In terms of antioxidant performance, it scavenges intracellular reactive oxygen species, inhibits lipid peroxidation and oxidative DNA damage, and enhances the body’s endogenous antioxidant defense system to delay aging processes. In addition, Alpinetin features significant broad-spectrum antibacterial activity against common pathogenic bacteria, and exhibits notable inhibitory effects on tumor cell proliferation, migration and invasion, supporting multi-scenario application in health care and pharmaceutical research.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our premium Alpinetin powder adopts low-temperature water-alcohol selective extraction and multi-stage high-precision column chromatography purification technology. We select high-quality Alpinia katsumadai raw materials with stable active content, completely remove plant fibers, macromolecular impurities, residual pigments and invalid components through gradient elution purification, and fully retain the natural flavanone active structure and biological activity of Alpinetin. The entire production process strictly avoids harmful solvent residues and chemical synthetic additives, fully complying with cosmetic-grade, food-grade and research-grade safety standards. The mature and stable production process ensures consistent batch purity, uniform powder appearance and reliable activity stability, meeting the strict formula development and experimental requirements of global customers.
Every batch of Alpinetin powder undergoes strict multi-dimensional quality inspection, including HPLC purity testing, UV spectral characteristic verification and NMR structural identification to ensure accurate molecular structure and stable high purity. The finished off-white crystalline powder features low impurity content, good solubility in organic solvents and excellent batch consistency. All products comply with international cosmetic additive regulations, natural functional ingredient safety standards and research-grade compound specifications, supporting safe and standardized application in skincare products, antibacterial preparations, health supplements and biomedical research projects.
We maintain sufficient inventory and complete qualification documents for bulk Alpinetin supply. Whether you need soothing anti-inflammatory and antibacterial raw materials for skincare formulas, antioxidant anti-aging ingredients for health products, or high-purity flavanone compounds for inflammation and tumor pharmacological research, our Alpinetin powder is a cost-effective and reliable bulk raw material choice for global buyers.
Functions & Benefits
Powerful Broad-Spectrum Anti-Inflammatory (Core Benefit)
Alpinetin is a natural high-efficiency anti-inflammatory flavanone. It targets the PPAR-γ/NF-κB dual pathway, significantly inhibiting the activation of inflammatory signaling pathways and reducing the release of TNF-α, IL-6 and other pro-inflammatory factors. It effectively relieves skin redness, swelling and sensitivity, improves chronic low-grade inflammation in the body, and achieves mild, long-lasting anti-inflammatory regulation without irritation.
Natural Broad-Spectrum Antibacterial Activity
Alpinetin exerts obvious inhibitory effects on a variety of common gram-positive and gram-negative pathogenic bacteria. It inhibits bacterial growth and reproduction, reduces bacterial-induced skin inflammation and body infection risks, and can be used as a safe natural antibacterial substitute for synthetic antibacterial agents in clean formula development.
High-Efficiency Antioxidant & Anti-Aging
This natural flavanone efficiently scavenges DPPH, ABTS and intracellular reactive oxygen free radicals, inhibits cellular lipid peroxidation and oxidative damage, reduces long-term oxidative stress aging, protects cell vitality, and delays skin and systemic aging processes, providing comprehensive antioxidant protection.
Anti-Tumor Proliferation & Cell Cycle Regulation
Modern pharmacological studies confirm that Alpinetin has significant anti-tumor activity. It blocks tumor cell cycle progression, inhibits tumor cell proliferation, migration and invasion, and induces tumor cell apoptosis. With low toxicity to normal human cells, it is an important research compound for anti-tumor auxiliary mechanism exploration.
Skin Barrier Repair & Soothing Stabilization
Alpinetin relieves skin inflammatory damage caused by external irritation, reduces sensitive skin reactions, enhances skin tolerance and barrier function, stabilizes skin microecology, and improves skin problems such as redness, sensitivity and dullness, suitable for sensitive skin soothing and repair formulas.
Metabolic Regulation & Organ Protection
Alpinetin assists in regulating lipid metabolism and relieving inflammatory damage to internal organs caused by metabolic disorders. It protects liver and kidney tissues from oxidative and inflammatory damage, providing natural sub-health conditioning and organ protection effects.
