Product Description

Our Pterostilbene powder is a high-purity natural trans-stilbene active ingredient, available in 98% and 99% HPLC grades. Pterostilbene (CAS 537-42-8), known as or 3,5-dimethoxy-4′-hydroxy-trans-stilbene, is a premium natural polyphenol compound enriched in blueberries and red sandalwood. As a superior methylated derivative of resveratrol, it features a unique dimethoxy substituted stilbene structure, delivering far higher bioavailability, metabolic stability and fat solubility than resveratrol. It integrates ultra-high-efficiency antioxidant, SIRT1-activated anti-aging, tyrosinase-inhibiting whitening, broad-spectrum anti-inflammatory, lipid-lowering hypoglycemic and neuroprotective effects, with outstanding anti-tumor pharmacological activity. Widely applied in high-end anti-aging skincare, longevity health supplements, metabolic conditioning products and advanced biomedical research. As a professional bulk Pterostilbene supplier, we provide high-purity, low-impurity, stable-batch natural stilbene raw materials for global industrial and scientific research clients.

Pterostilbene belongs to the trans-stilbene subclass of natural polyphenols, with a stable conjugated double bond and methoxy modified benzene ring structure. Different from resveratrol and conventional phenolic acids, Pterostilbene has core advantages of stronger stability, higher transdermal absorption and longer biological half-life. Its core functional mechanism targets the SIRT1/AMPK/mTOR longevity signaling pathway, effectively activating cell self-renewal and anti-aging mechanisms, delaying cellular senescence and skin photoaging. It significantly activates the Nrf2 endogenous antioxidant system to scavenge excess ROS free radicals, inhibit lipid peroxidation and oxidative cell damage. In skincare, it specifically blocks tyrosinase activity, inhibits melanin synthesis and UV-induced pigmentation, achieving safe and efficient brightening and whitening effects. In metabolic regulation, it optimizes lipid and glucose metabolism, improves insulin resistance and reduces body inflammation. In pharmacology, it inhibits malignant cell proliferation and invasion, induces tumor cell apoptosis, and exerts significant neuroprotective and cardiovascular protective effects, with ultra-high safety for long-term topical and oral application.

Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our premium Pterostilbene powder adopts low-temperature bio-enzymatic assisted extraction and multi-stage high-precision column chromatography purification technology. We select high-quality blueberry and red sandalwood plant raw materials with stable active content, completely remove plant fibers, macromolecular impurities, residual sugar and invalid pigments through gradient elution purification, and fully retain the complete trans-stilbene molecular structure and biological activity of Pterostilbene. 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 low solubility and easy oxidation of natural pterostilbene, ensures uniform powder appearance and stable activity, and meets the strict formula development and experimental requirements of global customers.

Every batch of Pterostilbene 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 white crystalline powder features low impurity content, good solubility in common organic solvents, strong stability and excellent batch consistency. All products comply with international cosmetic additive regulations, natural functional food safety standards and research-grade compound specifications, supporting safe and standardized application in high-end skincare products, anti-aging health supplements, functional foods and biomedical research projects.

We maintain sufficient inventory and complete qualification documents for bulk Pterostilbene supply. Whether you need high-efficiency whitening and anti-aging active raw materials for skincare formulas, SIRT1-activated longevity and metabolic conditioning ingredients for health products, or high-purity stilbene compounds for anti-inflammatory, anti-tumor and neuroprotective pharmacological research, our Pterostilbene powder is a cost-effective and reliable bulk raw material choice for global buyers.

Functions & Benefits

SIRT1 Activation & Advanced Anti-Aging (Core Benefit)

Pterostilbene is a powerful natural SIRT1 longevity pathway activator, efficiently regulating AMPK/mTOR signaling pathways to promote cell autophagy and repair senescent cells. It delays skin and organ natural aging, improves cellular vitality, and delivers long-lasting anti-aging and anti-senescence effects, being a premium longevity functional ingredient superior to ordinary antioxidants.

Ultra-High Antioxidant & Anti-Photoaging

With stronger free radical scavenging capacity than resveratrol and phenolic acids, Pterostilbene activates the Nrf2 antioxidant defense system, thoroughly eliminates intracellular ROS, inhibits lipid peroxidation and UV-induced oxidative damage, reduces skin light aging, fine lines and dullness, and forms a stable antioxidant protection barrier.

Tyrosinase Inhibition & Brightening Whitening

It specifically inhibits tyrosinase key enzyme activity, blocks the whole melanin synthesis chain, reduces UV-induced tanning and pigment deposition, fades chloasma and dull skin tone. With excellent transdermal permeability and stable whitening efficacy, it achieves mild, non-irritating and long-term skin brightening effects.

Broad-Spectrum Anti-Inflammatory & Skin Repair

Pterostilbene effectively inhibits NF-κB and MAPK inflammatory cascades, reduces the release of TNF-α, IL-6 and multiple pro-inflammatory factors, relieves acute UV inflammation and chronic low-grade skin inflammation, calms redness and sensitivity, and repairs damaged skin barrier function.

Metabolic Regulation & Cardiovascular Protection

Modern pharmacological studies verify that Pterostilbene significantly improves insulin resistance, regulates blood lipid and blood sugar balance, reduces LDL oxidation and vascular inflammatory damage, protects cardiovascular health, and effectively improves sub-health caused by metabolic disorders.

Anti-Tumor & Neuroprotective Activity

Pterostilbene inhibits the proliferation, migration and invasion of various malignant tumor cells, induces tumor cell apoptosis, and exerts broad-spectrum anti-tumor activity. Meanwhile, it protects nerve cells from oxidative stress damage, improves cerebral microcirculation, and delivers excellent neuroprotective effects.
