Abstract:

The objective of this study was to screen and assess the nutritional composition, phenolic, anthocyanin contents and antioxidant activity of various genotypes of apple growing in Rawalakot Azad Kashmir Pakistan. Vitamin C content, acidity %, reducing sugar and non reducing sugars were 11.4-14.2 mg/100 g, 0.21-0.44%, 9.66-7.23 mg/100 g and 1.63-2.66 mg/100 g. The aqueous extracts also showed high phenolic content (1.93-12 mg/g gallic acid equivalent), total antioxidant activity (65-155.3 µg/ml) and total monomeric anthocyanin (4.1-7.96 mg/L), respectively. The genotypes of apples, Golden delicious, Kala Kalu, Star King, Star King delicious, Chotta and Genotype-A, B and C, possess high radical scavenging activity in the 2,2-diphenyl-1-picrylhydrazyl assay. The evaluation of these genotypes not only provides important information regarding nutritional status of screened genotypes for the commercial exploitation, but also navigates the existing biodiversity in Malus domestica germplasm in these regions. The present results also suggest that different genotypes of apple are potential source of antioxidants and have therapeutic importance.
