Metabolomic and antioxidant analyses of Bunge and Hemsl. seeds.

and seeds are rich in metabolites that are beneficial to human health and can be utilised as nutritional supplements. In this study, UPLC-MS and GC-MS based on extensively focused metabolomics were used to compare the seed metabolomics of the two species. LC-MS detected 118 metabolites, primarily Lipids and phenylpropanoids. GC- MS detected a total of 188 metabolites, mainly organic acids and their derivatives, of which seeds contain high levels of nutrients. In addition, we experimentally determined antioxidant activity of two species, and the results showed that the antioxidant activity of seeds was about twice as high as that of seeds. We used WGCNA to group the metabolites, and found the central metabolites in the focal modules including flavonoids and terpenoids. Our study contributes valuable knowledge for future research on the chemical makeup of seeds.
