Resveratrol (RES) is a bioactive molecule with potent antioxidant properties, and it constitutes an essential component of herbal medicine. This study was designed to use a nano-syntheses approach to encapsulate RES in Poloxamer 407 nanoparticles. This type of nano-construction has been employed in a variety of biological applications, both in vitro and in vivo. The contribution of this nano-construct is to increase antioxidant activity over the pure RES was investigate. 1,1-diphenyl-2-picryl hydrazyl (DPPH), and hydrogen peroxide radical scavenging assays were utilized in vitro. RES-loaded poloxamer 407 showed concentration-dependent scavenging action in the range of 20-80 µg.ml-1, with a maximum activity of 80.1% at 80 µg.ml-1. Whereas pure RES had a decrement of 61.7%. While the activity of positive control (Vit. C) was 93.2%. The magnitude of blood hemolysis examination was 3.9% at 80 µg.ml-1. That may indicate RES-loaded poloxamer 407 provide significant red blood cell protection. The pure RES did not prevent the appearance of abnormal cells (echinocytes), and that was cured by RES-loaded poloxamer 407. Finally, the safety of RES-loaded poloxamer 407 was assessed in vivo. Male mice were invested to detect the functions of their liver and kidney. A histopathological study was included as well. The findings showed that RES-loaded poloxamer 407 might have superior characters as a drug delivery system, nutritional supplements, and may be used in pharmaceutical products.
