包装规格：20mg 250mg 1g in glass bottle
产品简介：一类在高等植物中广泛分布的多酚化合物，由亲电子黄烷酰基单元组成。Proanthocyanidin 可用作抗氧化剂和抗癌剂。Proanthocyanidin 还显示出抗炎，保护心脏，抗菌和抗真菌的特性，可用于研究慢性静脉功能不全、毛细血管脆弱、晒伤和视网膜病变。
溶解性：DMSO :100 mg/mL (Need ultrasonic) H2O : 5 mg/mL (ultrasonic and adjust pH to 11 with Na2CO3)
储备液保存：-80°C, 6 months -20°C, 1 month
体内实验：1、请依序添加每种溶剂： 10% DMSO→ 40% PEG300 →5% Tween-80→45% saline Solubility: 2.5 mg/mL (Infinity mM); Suspended solution; Need ultrasonic 此方案可获得 2.5 mg/mL (Infinity mM) 的均匀悬浊液，悬浊液可用于口服和腹腔注射。 以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。 2、请依序添加每种溶剂： 10% DMSO→90% (20% SBE-β-CD in saline) Solubility: ≥ 2.5 mg/mL (Infinity mM); Clear solution 此方案可获得 ≥ 2.5 mg/mL (Infinity mM，饱和度未知) 的澄清溶液。 以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中，混合均匀。 ＜1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得，实际溶液度可能与公布值有所偏差，属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液；⼀旦配成溶液，请分装保存，避免反复冻融造成的产品失效。
体外研究：Proanthocyanidin are present in plants as complex mixtures of polymers. Predominant food sources are red wine, tea, chocolate and fruits like grapes, apples, pears, and cranberries. The most interesting antibacterial activity of Proanthocyanidin is related to their presence in cranberries (Vaccinium macrocarpon Ait.). A number of clinical trials have demonstrated the effectiveness of cranberry consumption in preventing urinary tract infections (UTIs). Although UTIs can be caused by many microorganisms, more than 85% are caused by Escherichia coli. The presence of P-fimbriae on E. coli, which are proteinaceous fibers on the bacterial cell wall, has been clearly established as a virulence factor, since they are responsible by producing adhesions for adherence to uroepithelial cells. Recently, it is demonstrated that cranberry Proanthocyanidin might inhibit P-fimbriated E. coli from adhering to uroepithelial cells. The antiadhesion activity of cranberry juice appears to be related to the presence of Proanthocyanidin with at least one A-type linkage.
体内研究：The effects of cacao liquor Proanthocyanidin on 2- amino-1-methyl-6-phenylimidazo [4,5-b] pyridine-induced mutagenesis in vivo carcinogenesis in female Sprague-Dawley rats are investigated. In the Ames assay, Proanthocyanidin shows strong antimutagenic effects when assayed in the presence of S-9 mixture. They also inhibit significantly rat pancreatic carcinogenesis in the initiation stage, but not mammary carcinogenesis.
