植物提取物单宁的生物活性及其在水产养殖上的研究进展

Biological activities and research progress in aquaculture of plantextract tannin

单宁是普遍存在于自然界的一类多酚化合物,具有抗氧化、免疫刺激、抗菌、抗寄生虫等生物活性。长期以来,单宁被视为饲料"抗营养因子"。近年来研究表明,低剂量单宁有益于提高动物生长性能、增强机体抗氧化状态和调节肠道微生态平衡的功效。文章综述了植物提取物单宁的化学结构、生物活性及其在水产动物养殖上的应用研究进展,以期为单宁的饲料化开发利用提供依据。

Tannin is a class of polyphenolic compounds that are commonly found in nature. Tannin has been regarded as the ’anti-nutritional factor’ of feed. In recent years, research has shown that low-dose tannin is beneficial to improve animal growth performance, enhance the body’s antioxidant status, and regulate the intestinal microecological balance. The article reviews the chemical structure, biological activity of plant extract tannin and its application research progress in aquatic animal breeding, in order to provide a basis for the development and utilization of tannin in feed.
