    10 páginas.-- 3 figuras.-- 2 tablas.-- 40 referenciasThe aim of this study was to assess commercial quality parameters, sugars, phenolics, carotenoids and plastid in diverse and little studied tomato varieties to gain insight into their commercial and functional quality and reveal possible noticeable differences. Five cherry tomato varieties and six common (i.e., non-cherry) tomatoes were evaluated. The highest levels of lycopene were detected in ‘Tigerella’ and ‘Byelsa’ and those of phytoene in ‘Orangeʾ those of phenolics in ‘Green Zebra’ all of them common tomatoes. The levels of sugars in both groups of tomatoes were comparable. Interesting differences in plastid carotenoid-accumulating sub-structures as a function of the carotenoid profile were observed. Given the importance of chromoplasts in the deposition of carotenoids in plants and their release during digestion, this information can be valuable in investigations on the regulation of the biosynthesis and the bioavailability of tomato carotenoidsThe authors want to thank the Secretaría Nacional de Educación Superior, Ciencia, Tecnología e Innovación ( SENESCYT ) – Ecuador for its financial support and the Technical Staff of the Service of Biology (SGI, Universidad de Sevilla).
