HPLC analysis and in vitro antioxidant activities of Beta vulgaris juice (BVJ), dimercaptosuccinic acid (DMSA), and their combination (BVJ + DMSA) compared to ascorbic acid (Asc). Where (I): HPLC analysis of BVJ, (II): superoxide radical (O·‾) scavenging activitiy, (III): hydroxyl radical (OH۰) scavenging activity, (IV): α,α-diphenyl-β-picrylhydrazyl (DPPH) scavenging activity, and (V) nitric oxide (NO), scavenging activity. The results are shown as mean ± SE (n = 3). Different letters for the same parameter are significantly different at p < 0.05.
