Ambreen Naz, Masood Sadiq Butt, Imran Pasha and Haq Nawaz    

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.
