Research of tomatoes Solanum lycopersicum L. originating from different climatic-geographical regions and identification of metabolites by tandem mass spectrometry

Abstract

Relevance. A number of scientific studies confirm that consumption of fruits and vegetables can reduce the risk of certain chronic diseases, such as cancer and cardiovascular diseases, for example, consumption of fresh tomatoes and tomato products is inversely proportional to the development of certain types of cancer. Tomato Solanum lycopersicum L. contains a large number of polyphenolic complexes, which are biologically active compounds. In this article, the authors have attempted for the first time to present the complete metabolomic composition of Solanum lycopersicum extracts.Materials and methods: As an object of research, authors used the extracts of Solanum lycopersicum L., from the collection of the Federal Research Center N.I. Vavilov All-Russian Institute of Plant Genetic Resources, grown and collected at the Far Eastern Experiment Station Branch of the Federal State Budgetary Scientific Institution in September 2020 (varieties: k-5351 Ont77 13, Canada; k-3149 Rehovoth, Israel; 2698 Ukraine). High performance liquid chromatography (HPLC) in combination with a BRUKER DALTONIKS ion trap (tandem mass spectrometry) was used to identify target analytes in extracts obtained by the maceration method.Discussion: The results of initial studies revealed the presence of 36 biologically active compounds, of which 22 were identified for the first time in Solanum lycopersicum L. These are Apigenin, Luteolin, Kaempferol, Taxifolin, Myricetin, Coutaric acid, Caffeoylmalic acid, Caftaric acid, Dicaffeoylquinic acid, coumarins Fraxetin, and Fraxetin-7-O-beta-glucuronide, Pelargonidin, Salvianolic acid D, Rosmanol, Colnelenic acid, Ethyl rosemary, lignan Medioresinol-O-hexoside, Squalene, etc. The findings will help to intensify future research into the development and production of various functional food products containing targeted extracts of Solanum lycopersicum L.
