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) or butylated hydroxytoluene (BHT). (I) HPLC analysis of BVJ (II) ABTS+ radical scavenging activity (III) ferric reducing power (IV)β-carotene-linoleate bleaching activity (V) heat map plot of the in vitro antioxidant outcomes, the deep blue color refers to the higher IC50 value and the light color refers to the lower value. Results are shown as mean ± SE (n = 3). Different letters for the same parameter are significantly different at p < 0.05
