Analysis of Phenolic Metabolites for Rice Cultivar Breeding Fortified to Health-promoting in Selected Rice (Oryza sativa L.) Genetic Resources by LC-ESI-MS/MS

Rice (Oryza sativa L.) is one of the staple crop in the world as a resource of calories and nutrients. Recently phenolic metabolites increasingly appreciated as antioxidant nutrients, rice breeders have been making efforts to make valuable character containing antioxidant compounds in grain as well as high yield. This study aimed to examine the quantitative composition of phenolic metabolites in the selected Korean rice genetic resources to construct an integrative omics database for development of new rice breeding system. The analysis was conducted by LC-ESI-MS/MS in multiple reactions monitoring mode targeting 55 phenolic metabolites and two amino acid precursors.
