Product Description
Our Farrerol powder is a high-purity natural flavanone active ingredient, available in 98% and 99% HPLC grades. Farrerol (CAS 24211-30-1), commonly known as 杜鹃素, is a signature bioactive compound isolated from the traditional Chinese medicinal herb Rhododendron dauricum. Possessing a unique dimethyl-substituted flavanone structure, Farrerol delivers excellent molecular stability and multi-dimensional pharmacological activity, standing out among natural plant flavonoids for its potent antioxidant, anti-inflammatory, hepatoprotective, neuroprotective and anti-tumor properties. It is widely applied in soothing skincare formulas, liver-protective health supplements, nerve-nourishing functional products and biomedical pharmacological research. As a professional bulk Farrerol supplier, we provide high-purity, stable-batch and fully compliant products for global industrial and scientific research clients.
Farrerol belongs to the flavanone subclass of flavonoids, with unique structural advantages that endow it with higher bioavailability than ordinary flavonoid ingredients. Its core functional mechanism centers on activating the Nrf2/HO-1 antioxidant signaling pathway, efficiently scavenging intracellular reactive oxygen species and enhancing the body’s endogenous antioxidant defense system. Meanwhile, Farrerol significantly inhibits the NF-κB inflammatory cascade, reduces the release of multiple pro-inflammatory cytokines, and relieves acute and chronic low-grade inflammation without irritation or side effects. In terms of organ protection, it protects liver cells from oxidative damage and toxic injury, improves liver metabolic function, and exerts excellent neuroprotective effects by inhibiting neuronal apoptosis and oxidative stress. In addition, Farrerol presents notable inhibitory activity against tumor cell proliferation and migration, supporting in-depth development of anti-tumor pharmacological research and functional formulas.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our premium Farrerol powder adopts low-temperature water-alcohol selective extraction and multi-stage high-precision column chromatography purification technology. We select high-quality Rhododendron dauricum 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 Farrerol. 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 Farrerol 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, health supplements and biomedical research projects.
We maintain sufficient inventory and complete qualification documents for bulk Farrerol supply. Whether you need anti-inflammatory and antioxidant raw materials for skincare formulas, liver and nerve protective ingredients for health products, or high-purity flavanone compounds for inflammation, oxidation and tumor pharmacological research, our Farrerol powder is a cost-effective and reliable bulk raw material choice for global buyers.
Functions & Benefits
Powerful Nrf2-Mediated Antioxidant (Core Benefit)
Farrerol is a high-efficiency natural antioxidant that specifically activates the Nrf2/HO-1 signaling pathway. It efficiently scavenges DPPH, ABTS and intracellular reactive oxygen free radicals, inhibits cellular lipid peroxidation and oxidative DNA damage, enhances the body’s endogenous antioxidant capacity, reduces long-term oxidative stress aging, and provides comprehensive cellular antioxidant protection.
Broad-Spectrum Anti-Inflammatory Activity
This natural flavanone effectively inhibits the activation of NF-κB inflammatory pathway, significantly reducing the release of TNF-α, IL-6 and other pro-inflammatory factors. It relieves skin redness, swelling and sensitivity, improves chronic low-grade inflammation in the body, and achieves mild, long-lasting anti-inflammatory regulation without causing skin irritation or side effects.
Excellent Hepatoprotective Effect
Farrerol protects liver parenchymal cells from oxidative damage and chemical toxic injury, inhibits liver cell apoptosis and inflammatory infiltration, improves liver microcirculation and metabolic function, reduces liver oxidative degeneration risk, and is a safe and effective natural liver-protective active ingredient.
Significant Neuroprotective Properties
Modern pharmacological studies verify that Farrerol can inhibit neuronal oxidative stress damage and apoptosis, stabilize nerve cell activity, improve cerebral microcirculation, relieve nerve cell damage caused by oxidative stress, and provide effective nutritional protection for nerve tissue, with broad prospects in neuro-health product development.
Anti-Tumor Proliferation & Metabolic Regulation
Farrerol inhibits the proliferation, migration and invasion of various tumor cells, blocks abnormal tumor cell cycle progression, and induces tumor cell apoptosis with low toxicity to normal human cells. It also assists in regulating body lipid metabolism and relieving metabolic disorder-induced sub-health problems.
Skin Soothing & Barrier Repair
Farrerol relieves skin inflammatory irritation and oxidative damage caused by external stimuli, reduces sensitive skin reactions and redness dullness, enhances skin barrier tolerance and self-repair ability, stabilizes skin microecology, and improves various sensitive skin problems.
