Product Description
Our Geraniin powder is a high-purity natural ellagitannin active ingredient, available in 98% and 99% HPLC grades. Geraniin (CAS 60976-49-0), known as 老鹳草素, is a unique high-molecular-weight polyphenol compound widely enriched in Geranium herbs and maple leaves. As a classic representative of natural ellagitannins, it features a complex multi-phenolic hydroxyl structure, delivering far stronger comprehensive antioxidant and anti-inflammatory activity than conventional flavonoids and ordinary tannins. It integrates multi-core efficacy including ultra-high-efficiency free radical scavenging, broad-spectrum anti-inflammation, tyrosinase inhibitory whitening, natural hypoglycemic regulation, antiviral defense and cell anti-aging protection. Widely applied in high-end soothing whitening skincare, blood sugar balancing health supplements, antiviral functional foods and advanced biomedical pharmacological research. As a professional bulk Geraniin supplier, we provide high-purity, low-impurity, stable-batch natural ellagitannin raw materials for global industrial and scientific research clients.
Geraniin belongs to the high-activity ellagitannin subclass of natural polyphenols, with a unique hydrophilic multi-hydroxyl molecular structure and excellent biological compatibility. Different from stilbenes, lignans and phenolic acid ingredients, Geraniin has excellent water-soluble polarity, dual anti-oxidation & anti-glycation capabilities and exclusive natural alpha-glucosidase inhibitory activity. Its rich phenolic hydroxyl groups can rapidly capture intracellular ROS free radicals, block lipid peroxidation and glycation reaction chains, effectively improving skin oxidative aging and dull yellowing caused by glycosylation. In skincare, it inhibits tyrosinase activity to reduce melanin deposition, relieves UV-induced inflammatory redness and sensitive irritation, and repairs damaged skin barriers. In metabolic regulation, it targets intestinal alpha-glucosidase to delay carbohydrate decomposition, significantly reduce postprandial blood sugar spikes, and improve insulin resistance. In pharmacology, it exerts broad-spectrum antiviral, anti-tumor and neuroprotective effects, with mild properties and ultra-high safety for long-term topical and oral application.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our premium Geraniin powder adopts low-temperature solvent directional extraction and multi-stage high-precision column chromatography purification technology. We select high-quality wild Geranium herb raw materials with stable tannin content, completely remove plant fibers, macromolecular proteins, residual impurities and invalid tannin polymers through gradient elution purification, and fully retain the complete ellagitannin molecular structure and biological activity of Geraniin. 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 refined purification process solves the problems of impure traditional tannin extracts and unstable activity, ensures uniform white crystalline powder appearance and consistent batch efficacy, meeting the strict formula development and high-precision experimental requirements of global customers.
Every batch of Geraniin powder undergoes strict multi-dimensional quality inspection, including HPLC high-precision purity testing, UV spectral characteristic verification and NMR structural identification to ensure accurate molecular structure and stable high purity. The finished powder features low impurity content, good solubility in polar solvents, strong structural stability and outstanding batch consistency. All products comply with international cosmetic additive regulations, natural functional food safety standards and high-end research-grade compound specifications, supporting safe and standardized application in whitening soothing skincare, blood sugar regulation health products, antiviral functional foods and cutting-edge biomedical research projects.
We maintain sufficient inventory and complete qualification documents for bulk Geraniin supply. Whether you need anti-oxidation, anti-glycation and whitening active raw materials for high-end skincare formulas, natural hypoglycemic and metabolic conditioning ingredients for health products, or high-purity ellagitannin compounds for antiviral, anti-tumor and pharmacological mechanism research, our Geraniin powder is a cost-effective and high-value bulk raw material choice for global buyers.
Functions & Benefits
Ultra-Strong Antioxidant & Anti-Glycation Anti-Aging (Core Benefit)
Geraniin possesses powerful DPPH, ABTS and superoxide anion free radical scavenging capacity, efficiently eliminates intracellular oxidative stress, and inhibits lipid peroxidation. Different from ordinary antioxidants, it significantly blocks skin glycation reactions, reduces AGEs deposition, improves skin yellowing, relaxation and dullness caused by glycation aging, and achieves dual anti-oxidation and anti-glycation deep anti-aging effects.
Tyrosinase Inhibition & Mild Brightening Whitening
It specifically inhibits the catalytic activity of tyrosinase, the core enzyme of melanin synthesis, blocks the melanin production pathway from the source, reduces UV-induced tanning and pigmentation, and fades uneven skin tone. With mild non-irritating properties and excellent skin affinity, it realizes long-term stable brightening and whitening without damaging the skin barrier.
Broad-Spectrum Anti-Inflammatory & Sensitive Skin Soothing
Geraniin effectively inhibits NF-κB and MAPK inflammatory signaling pathways, reduces the release of TNF-α, IL-6 and various pro-inflammatory factors, relieves acute UV inflammation and chronic low-grade skin inflammation, calms sensitive redness and swelling, stabilizes skin microecology, and repairs fragile sensitive skin barriers.
Natural Alpha-Glucosidase Inhibition & Hypoglycemic Regulation
As a natural carbohydrate digestive enzyme inhibitor, Geraniin efficiently inhibits intestinal alpha-glucosidase activity, delays starch and sucrose decomposition and absorption, suppresses postprandial blood sugar spikes, improves insulin resistance, and assists in balancing blood sugar metabolism and preventing metabolic syndrome.
Broad-Spectrum Antiviral & Immune Enhancement
Modern pharmacological studies verify that Geraniin has significant inhibitory activity against multiple viruses. It regulates body immune balance, reduces inflammatory damage caused by viral invasion, enhances systemic immune defense capability, and provides natural antiviral protection for daily health care.
Anti-Tumor & Neuroprotective Activity
Geraniin inhibits the proliferation and migration of various malignant tumor cells, induces tumor cell apoptosis, and exerts broad-spectrum anti-tumor chemoprevention effects. Meanwhile, it protects nerve cells from oxidative and inflammatory damage, improves cerebral microcirculation, and relieves neuro-aging sub-health problems.
