Abstract
Quantitative analysis of vitamin A, vitamin C, and mineral contents in two different cultivars of pumpkins (Cucurbita moschata), which were local `Golden Cushaw' and Australian 'Butternut', were carried out. Vitamin A was analyzed using High Performance Liquid Chromatography (HPLC) while vitamin C was analyzed according to the iodometric back-titration method. Minerals were analyzed by using Atomic Absorption Spectrophotometric (AAS) and phosphorus was analyzed using UV-Vis Spectrophotometer. Based on the results obtained, 100 g of 'Golden Cushaw' flesh contained 5286 IU of vitamin A, 13.99±1.35 mg vitamin C, 6.17±0.21 mg sodium, 412.29±33.30 mg potassium, 40.16±1.74 mg magnesium, 54.46±4.17 mg calcium, 0.32±0.02 mg iron, 0.20±0.02 mg zinc, and 21.33±0.29 mg phosphorus; while 100 g of 'Butternut' contained 4533 IU of vitamin A, 15.75±1.45 mg vitamin C, 3.80±0.36 mg sodium, 291.67±1.38 mg potassium, 48.33±9.79 mg magnesium, 38.83±1.47 mg calcium, 0.29±0.01 mg iron, 0.19±0.02 mg zinc, and 48.83±0.55 mg phosphorus. The results showed that the 'Golden Cushaw' had the higher nutrition values compared to the 'Butternut'.
