Metabolite Profiling of Tomato (Solanum lycopersicum L.) Germplasms Using LC-MS Analysis

Abstract

Eleven tomato genotypes collected from different districts of Meghalaya were evaluated based on the analysis of metabolic characters of chemical parameters/constituents using Liquid Chromatography mass-spectrometry (LCMS) analysis. In the current study, a total of 19 primary metabolites, 2 common primary metabolites, 5 uncommon primary metabilotes, 24 secondary metabolites, 5 common secondary metabolites and 4 uncommon secondary metabolites were detected in 11 samples of tomato. It was observed that the detected primary metabolites and secondary metabolites of different tomato samples was found to have beneficial health effects. It was observed that the egg-shaped tomato genotype collected from Resubelpara (Sample No 3) contained two carcinogenic metabolites including five health-promoting metabolites. Accordingly, the 11 tomato genotypes have been arrranged in descending order based on their effects on human health as follows, Sample No-9 > sample No-5 > sample No-7 > sample No-4 > sample No-1 > sample No-8 > sample No-2 > sample No-6 > sample No-10 > sample No-11 > sample No-3. Based on the comparative study, it was concluded that the egg-shaped tomato genotype collected from Nongpoh (Sample No 9) contained twenty-one numbers of good metabolites with medicinal values and also it was observed that these metabolites was found very essential for human growth and development. As a result, the tomato genotype collected from Nongpoh (Sample No 9) was found to be the best among the other samples of tomato genotypes.
