The studies were done on three varieties of tomatoes from Spain (red cherry, yellow cherry and kumato cherry). The following parameters: pH, soluble solids, content of water (moisture), content of minerals (ash), titratable acidity and content of some bioactive compounds (vitamin C, polyphenols, flavonoids, anthocyanins and carotenoids) were determinate in order to appreciate the quality of these products. The results showed the influence of the varieties on the values of bioactive compounds with antioxidant activity.
