Bioactive compounds in tomato (Solanum lycopersicum) variety saladette and their relationship with soil mineral content.

The purpose of this study was to determine the relationship between the mineral composition of soils and the bioactive compound content present in tomatoes grown in three regions of Mexico: the state of San Luis Potosí and Tultitlán and Cuautitlán Izcalli from the State of México: Total phenolic compounds, lycopene, and rutin were higher in the Tultitlán tomatoes and were associated with the thallium and magnesium content in the soil. Chlorogenic acid and quercetin in the fruit from C.IZC were associated with molybdenum and nickel found in the soil.

Relationship between the elemental composition of grapeyards and bioactive compounds in the Cabernet Sauvignon grapes Vitis vinífera harvested in Mexico.

The red grape Vitis vinífera is an important source of phenolic compounds, which can prevent disease if included as a part of a diet. The levels of these compounds in grapes have been associated with various environmental factors, such as climate, soil composition, and biotic stress. The purpose of this study was to determine the relationship between the elemental compositions of the soil and the grapes and the presence of bioactive compounds, such as catechin, epicatechin, piceid and resveratrol.

Preparation of a porous clay heterostructure and study of its adsorption capacity of phenol and chlorinated phenols from aqueous solutions.

A porous clay heterostructure (PCH) from a Mexican clay was prepared and characterized, and its aqueous phenol and dichlorophenols (DCPs) adsorption capacities were studied using a batch equilibrium technique. The PCH displayed a surface area of 305.5 m2/g, 37.
