99% Pterostilbene粉

Pterostilbeneは何ですか?

Pterostilbene 化学成分は、赤い白檀に含まれていますが、科学者はpterostilbeneの存在を発見しましたか 他の植物では、最初にローズウッドで発見されたため、pterostilbeneと命名された。Pterostilbene 白色またはオフホワイトの粉末の結晶は、豊富な薬効があり、抗真菌性の有効成分に属し、癌、高血圧、高血圧、高血脂肪治療に一定の効果があります。近年、プテロスチルベンの工業的合成法が確立された。

トランス-スチルベンアナログとして、pterostilbene レスベラトロールのメチル化誘導体であり、抗酸化、抗腫瘍、脂質低下、静菌などのさまざまな生物学的活性を有し、レスベラトロールよりも生物学的利用可能で安定しています。

グリーンスプリング技術は、新しいリポソーム技術を利用してpterostilbene powder 99%を提供し、pterostilbene powder nano-embeddingを実現し、pterostilbeneの低い生物学的利用能と不溶性を効果的に改善し、その経皮吸収効果と適合性を大幅に向上させます。このpterostilbene粉末の溶解度は良好で、リポソーム技術は効果的にpterostilbeneの低い溶解度の問題を改善します;安定性に優れ、リポソーム技術は良好な保護効果を有し、カプセル化後のpterostilbeneの安定性が大幅に向上しています。

2000年に設立されたグリーンスプリング技術は、天然植物抽出物の研究開発、生産、販売に専念する技術主導型ハイテク企業です。完璧な品質管理システムを持ち、iso、haccp、およびその他の品質基準に従って生産を組織しています。グリーンスプリングは7つの認証と7つの特許を保有しており、製品は世界62カ国で販売され、2450社以上の顧客にサービスを提供している。halal、kosher、cosmos、brc、ifs、fda、isoなど多くの認証を取得しています。

Benefits:

Antioxidant

Pterostilbene has been shown to help reduce free radical damage. When compared to tetrahydrocurcumin, photoglycopyrrolidine, and vitamin C, astragalus has the strongest oxygen radical uptake; and has a strong ability to inhibit DPPH free radicals, which suggests a superb antioxidant effect. In published studies, pterostilbene has been found to display direct antioxidant effects while also modulating antioxidant enzymes and defense systems throughout the body. No known botanical ingredient has surpassed this to date.

Inhibition of Melanin

Pterostilbene is a unique autophagy inducer, that can effectively induce cytoprotective autophagy in human umbilical vein endothelial cells by rapidly increasing intracellular calcium concentration and AMPKa1 activation, and thus inhibiting mTOR, a negative regulator of autophagy. Pterostilbene plays an inhibitory role against melanogenesis by down-regulating proteins involved in α-MSH-triggered B16-F10 cells and induces resistance through autophagy to melanogenesis.

Spot Removal

In the assay experiments for the efficacy of spot removal, the untreated cells had obvious black spots; while the cells were treated with 0.55 μg/ml of pterostilbenes (90%), used every 3 days for 9 days, and eventually the black spots disappeared, indicating that it has a good effect of spot removal.

Whitening

Pterostilbene has excellent melanin and complexin inhibiting effects. Studies have shown that it inhibits melanogenesis, melanocyte dendrites and melanosome transport via the cAMP/PKA/CREB pathway. Its half inhibitory concentration IC50 value for tyrosinase is significantly better than that of common whitening ingredients such as vitamin C and arbutin, and only slightly lower than that of photoglycoside. When compared with whitening ingredients such as glycyrrhizin, tretinoin and vitamin C, pterostilbene has the most significant melanin inhibiting effect. Not only that, pterostilbene can also promote cell autophagy and effectively metabolize melanin and lipofuscin that have already been generated in the skin, so its whitening speed is more rapid than that of common whitening ingredients.

Protects against UV Damage

Studies have shown that pterostilbene can express antioxidant enzymes and has good UVB protective efficacy. In cellular experiments, 30 μg/mL of pterostilbene can reduce half of the cytotoxic damage caused by UVB; and a low concentration of 4 μmol/L of pterostilbene pretreatment can inhibit the DNA damage of skin cells by UVA irradiation. In addition, the use of the sun protection factor (SPF value) test in human experiments revealed that the SPF value of the cream containing 0.4% pterostilbene was 6.2, which demonstrated the effect of pterostilbene as a natural sunscreen.

Anti-Inflammatory

Through the regulation of the Nrf2 pathway, pterostilbene can effectively inhibit the expression of inflammatory factors such as COX-2, PGE2, and NO, demonstrating excellent anti-inflammatory effects. Meanwhile, pterostilbene is also able to reduce intracellular inflammatory responses and reactive oxygen species (ROS) levels and inhibit neutrophil activation, inflammatory mediator production, and endothelial cell apoptosis.

Applications:

In Cosmetics:

According to domestic and international research reports, pterostilbene possesses a variety of skincare effects such as whitening, antioxidant, anti-inflammatory, anti-glycation, defense against UV damage as well as firming and anti-wrinkles, and is considered one of the most all-round whitening and anti-aging cosmetic ingredients. Pterostilbene powder has been used as an ingredient in various high-end cosmetic formulations.
