Sažetak
The fruits of grapefruit are characterised by a rich nutritional composition, especially the vitamin C content, polyphenolic compounds and a strong antioxidant activity. The composition and phytochemicals largely content depend on the genetic characteristics of the species or cultivar. Therefore, the aim of this study was to determine the physicochemical properties, bioactive compound content and antioxidant potential of grapefruit fruits of two different cultivars: 'Marsh Seedless' and 'Natzumikan'. Both grapefruit cultivars were harvested from a citrus orchard in the Opuzen region. The studied varieties did not differ significantly in the total dry matter content (average determined value 11.55%), total soluble solids (average determined value 9.89%), as well as in the of vitamin C content (average determined value 42.92 mg/100 g fresh matter). However, significant differences were found in the polyphenolic compounds content, with the variety 'Natzumikan' having as much as 66% more total phenols, 76% more total flavonoids and 54% more total non flavonoids compared to the variety 'Marsh Seedless'. Moreover, the cultivar 'Natzumikan' had significantly higher antioxidant capacity (1.68 mmol TE /L). From all this, it can be concluded that grapefruit fruit is a significant source of valuable phytochemicals important for human health.
