Antioxidant Indices of Watermelon Juice and Lycopene Extract
Abstract
In the current project, indigenously grown promising watermelon variety (Sugar baby) was characterized for its antioxidant potential. The watermelon juice and lycopene extract were quantified by HPLC that depicted 4.53±0.05 and 6.27±0.06 mg/100mL of lycopene, respectively. Furthermore, the watermelon juice and lycopene extract showed Total Phenolic Contents (TPC), beta-carotene assay, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Ferric Reducing Antioxidant Power (FRAP) as 23.63±1.09 and 97.15±5.01 mg/100g GAE, 49±3.10 and 73±3.20%, 29.11±1.91 and 57±3.22% and 21.67±1.21 and 37.60±1.12 mM FRAP/g, respectively. Consequently, the watermelon proved as a good source of antioxidant with special reference to lycopene.
