Comparative Metabolomics Analysis of Flavonoid Metabolites in Different Cultivated Beets
[Objective]The purpose of this study was to analyze the flavonoid components and their differences in sugar beet and red beet root.[Methods]The flavonoids in two kinds of beet root were compared by comparative metabolomics.[Results]A total of 69 flavonoids of 6 kinds were detected in two kinds of beetroot.There were 30 differential substances.According to the metabolite Log2FC,there were 6 components with large difference ratio,which were polymethyl flavonoid derivatives,isorhamnoside and rhamnoside,marigold glycoside,geranylside and chrysanthin.In red beet root,5 kinds of differential metabolites content were higher than those in sugar beet roots,and 25 kinds of differential metabolites content was lower than those in sugar beet root.Compared with sugar beet root,the components with higher content of flavone metabolites in red beet root were vitexin,isovitexin glucoside and apigenin glucoside.In the biosynthetic pathways of flavonoids and flavonols,seven substances were annotated to the KEGG pathway.[Conclusion]There were significant differences of flavonoids in two kinds of beet materials,which could be used as characteristic substances for further analysis.
