The preservation of fresh produce served as salads through soaking with solutions containing naturally occurring phenolic ingredients is of merit. For a primary assay, thymol and resveratrol at 0-500 ppm were prepared and used to inhibit growth and survival of and . Thymol and resveratrol exhibited potent inhibitory activities against the growth of both bacteria. For , cells treated with thymol at 250 ppm or resveratrol at 500 ppm, the durations to achieve 3 log reduction (3LR) were 40 and 20 min, respectively. When the cells were treated with thymol combined with resveratrol, both at 250 ppm, the 3LR value was achieved in under 5 min Synergistic antibacterial activity between thymol and resveratrol was apparent. The antibacterial and known health-enhancing activities of resveratrol are of interest.

Inflammatory bowel disease (IBD) is a chronic, relapsing gastrointestinal (GI) disorder characterized by intestinal inflammation. The etiology of IBD is multifactorial and results from a complex interplay between mucosal immunity, environmental factors, and host genetics. Future therapeutics for GI disorders, including IBD, that are driven by oxidative stress require a greater understanding of the cellular and molecular mechanisms mediated by reactive oxygen species (ROS).
