Studies have shown that the tomato (Solanum lycopersicum), constitutes an excellent natural source of antioxidants, most of these substances are found in the skin and the seeds, but not in the fruit pulp. These compounds content in the fruit is associated to different factors such as weather, growth time, soil, among others. In Mexico, there are regions where tomatoes are grown, that are considered saline due to its elemental composition, this can contribute to the synthesis of different bioactive compounds. This research shows evidences of the relationship between the mineral composition of the soil and the fruit, with the lycopene, rutin, chlorogenic acid, quercetin and resveratrol content on the tomato. There were determined, the physicochemical characteristics and the elemental analysis, of three different greenhouse soils where tomatoes are grown, from three different regions of the country, San Luis Potosi (SLP), Tultitlan (TUL) and Cuautitlan Izcalli (C.IZC); also, there were determined the physicochemical characteristics, antioxidant activity, phenolic compounds content (total and individual), which were determined by HPLC of the fruit grown in the above mentioned soils. The phenolic compound content was higher in the tomatoes from TUL (47.82 mgEAG/100g), just as the lycopene content (89.38 mg/kg) and rutin (11.53 mg/kg), related to a high content of Thallium (0.0086 mg/g) and Magnesium (670.13 mg/g), that were present in the soil of that region.
