白藜芦醇生物学活性及其在水产动物中的应用

白藜芦醇(resveratrol, RES)是一种多酚类防御素, 广泛存在于葡萄、虎杖及蓝莓等多种植物之中。RES 因具有抗氧化、抗炎、抗细菌、免疫调节等生物学活性而被作为新型绿色饲料添加剂应用于水产行业中。本文综述了 RES 的理化性质、生物利用率、生物学活性及其调节机制, 并总结了 RES 在水产养殖中的应用。结果表明, 适宜浓度的 RES 对水产动物的生产性能、免疫健康及脂肪代谢调节均有良好地促进作用; 此外, RES 还可有效防控细菌病原体对水产动物的侵染。但基于目前的研究, RES 发挥生物学功能的相关机制尚未充分清楚, 针对不同水产动物的适宜剂量也缺乏基础性研究, 应尽快开展深入研究以期为进一步促进 RES 在水产动物中的应用提供参考。

Resveratrol biological activities and its application in aquatic animals

Resveratrol (RES) is a type of polyphenolic defense compound that is widely found in many plants, such as grapes, knotgrasses, and blueberries. RES has been used as a new green feed additive in the aquatic industry due to its biological activities, such as anti-oxidation, anti-inflammation, anti-bacteria, and immune regulation. The physicochemical properties, bioavailability, biological activities, and regulatory mechanism of RES are summarized in this article, and the application of RES in aquatic production is also summarized. The results showed that appropriate concentrations of RES were beneficial to the production performance, immune health, and fat metabolism regulation in aquatic animals. In addition, RES could effectively prevent bacterial pathogens from infecting aquatic animals. However, the mechanism underlying its biological activities is still not fully understood, and there is a lack of basic research on the appropriate dose for different aquatic animals. In-depth research should be carried out as soon as possible in order to provide reference for further promoting the application of RES to aquatic animals.
