摘要:

鞣花单宁和鞣花酸是广泛分布于多种蔬菜、水果和坚果中的多酚类抗氧化剂,其在胃肠道的吸收较差,生物利用率较低,但部分会被哺乳动物肠道微生物转化为更易吸收的尿石素类代谢产物。因此,人们推测这些代谢产物可能为鞣花单宁及鞣花酸发挥生物学活性的最终物质基础。本文对近年来国内外有关尿石素化学性质和抗氧化、抗炎、抗癌以及调节肠道菌群等生物活性的研究进行综述,以期为富含鞣花单宁及鞣花酸类食品的科学利用提供借鉴。

Abstract:

Ellagitannins and ellagic acid are natural polyphenols widely distributed in pomegranate, strawberry, raspberry,
blackberry, grape and walnut. However, the absorption of ellagitannins and ellagic acid is extremely poor and the
unabsorbed ellagitannins and ellagic acid can be further metabolized to urolithins by the gut microbiota in the colon. It is
therefore conceivable that the health effects of ellagitannins-containing products can be associated with the gut-produced
urolithins, and thus, the evaluation of biological effects of these metabolites is essential. The present review covers the
recent studies concerning the chemical properties and biological activities of urolithins.

Key words: urolithins, ellagic acid, antioxidant, anti-inflammatory, anticancer
