Pterostilbene 분말 99%

Pterostilbene란?

Pterostilbene 붉은 샌달우드에 포함된 화학 성분이지만 과학자들이 pterostilbene의 존재를 발견했습니다 다른 식물에서도 그렇지만 로즈우드에서 처음 발견되었기 때문에 pterostilbene 라는 이름이 붙여졌다.Pterostilbene 흰색 또는 off-white 분말 결정이며, 풍부한 약용 가치를 가지고 있으며, 항진균 활성 성분에서 혈액 배기 제품에 속하며, 암, 고혈압, 고혈압,고 혈액 지방 치료에는 일정한 효과가 있습니다.최근, 연구원들은 pterostilbene의 산업 합성 방법을 마스터했습니다.

trans-stilbene 아날로그로서, pterostilbene 레스베라트롤의 메틸화 유도체로 항산화, 항암, 지질 저하 및 박테리아성 등의 다양한 생물학적 활성을 가지며 레스베라트롤보다 생물학적 이용이 가능하고 안정적입니다.

그린스프링 기술은 새로운 리포좀 기술을 활용해 Pterostilbene 파우더 나노 임베딩을 실현해 Pterostilbene의 낮은 생체 가용성과 낮은 용해도를 효과적으로 개선하고, 경피 흡수 효과와 호환성을 대폭 향상시키는 Pterostilbene 파우더 99%를 공급한다.리포좀 기술이 효과적으로 pterostilbene의 낮은 용해도 문제를 개선하기 때문에이 pterostilbene 분말의 용해도는 좋다;안정성이 우수하고 리포좀 기술이 보호 효과가 좋으며 캡슐화 후 pterostilbene의 안정성이 대폭 향상되었습니다.

2000년에 설립된 그린스프링테크놀로지는 천연식물추출물의 연구 개발, 생산, 판매를 전담하는 기술주도형 하이테크 기업이다.완벽한 품질 관리 시스템을 갖추고 ISO, HACCP 및 기타 품질 표준에 따라 생산을 조직합니다.그린스프링은 7개의 인증서와 7개의 특허를 보유하고 있으며, 제품은 전세계 62개국 이상에서 판매되어 2450개 이상의 고객에게 서비스를 제공하고 있으며 좋은 평가를 받고 있다.우리는 Halal, Kosher, COSMOS, BRC, IFS, FDA, ISO 및 기타 많은 인증을 통과했습니다.

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.
