Purple and Yellow P. edulis had significantly higher total sugar, 142.85 ± 0.17 g kg−1and 139.69 ± 0.12 g kg−1,respectively, than other cultivars. Glucose and fructose content were higher in juice from vine-ripened fruits of Purple, Frederickand Yellow P. edulis, P. quadrangularis and P. maliformis. Sucrose content was significantly higher in juice of non-vine-ripenedfruits of P. edulis (Pink) and P. edulis f. flavicarpa. Ascorbic acid, TPC and TAA were significantly higher in vine-ripened Purple andYellow P. edulis; ranges were 0.22–0.33 g kg−1, 342.80–382.00 mg gallic acid equivalent L−1and 409.13–586.70 µmol TroloxL−1, respectively. Based on principal component analysis (PCA) and cluster analysis, the main variables –◦Brix, total sugar,glucose, fructose, ascorbic acid, TPC and TAA – formed the characteristics for the group comprising Purple and Yellow P. edulis.
