摘要

鞣花酸（EA）是一种天然抗氧化剂，存在于许多水果和蔬菜中。然而，它在水中的溶解度很低，这限制了它的应用。为了克服这一限制，我们使用了表面活性剂 Span 20 和 Tween 60 来增加其在水中的溶解度。傅立叶变换红外光谱、TEM 和激光粒度及 zeta 电位分析用于表征鞣花酸乳液的形态和结构。采用 DPPH 和 ABTS 自由基清除、还原力和总抗氧化活性等多种抗氧化评价方法测定了与表面活性剂兼容的鞣花酸的抗氧化活性。结果表明，加入司盘 20 和吐温 60 后，鞣花酸在水中的溶解度得到改善，鞣花酸与司盘 20 和吐温 60 结合后形成复合颗粒。与纯鞣花酸相比，鞣花酸乳液的抗氧化活性明显提高。

Effect of solubilization with surfactant on the antioxidant activity of ellagic acid

Ellagic acid (EA) is a natural antioxidant found in many fruits and vegetables. However, its solubility in water is poor, which limits its application. To overcome this limitation, the surfactants Span 20 and Tween 60 are used to increase its solubility in water. FTIR, TEM and laser particle size and zeta potential analysis were used to characterize the morphology and structure of ellagic acid emulsions. The antioxidant activity of surfactant-compatible ellagic acid was determined using various antioxidant evaluation methods such as DPPH and ABTS radical scavenging, reducing power and total antioxidant activity. The results indicate that the solubility of ellagic acid in water was improved by the addition of Span 20 and Tween 60, and ellagic acid formed complex particles in combination with Span 20 and Tween 60. Compared to pure ellagic acid, the antioxidant activity of ellagic acid lotion was significantly enhanced.
