生物活性

Proanthocyanidins 是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。Proanthocyanidins 可用作抗氧化剂和抗癌剂。Proanthocyanidins 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。

体外研究

Proanthocyanidins 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 Proanthocyanidins 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 Proanthocyanidins 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 Proanthocyanidins with at least one A-type linkage.

体内研究

The effects of cacao liquor Proanthocyanidins 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, Proanthocyanidins 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.
