Variation of the content of anthocyanins and flavonols in the accessions of shallot and A. x wakegi collected in Indonesia, Japan and Korea was investigated. Cyanidin was the dominant anthocyanins in both shallot and A. x wakegi. Peonidin was also detected in a small amount only in two shallot and one A. x wakegi accessions and in a trace amount in all other accessions. Only quercetin was detected as a flavonol and it distributed with wide variation in either species. A. x wakegi accessions showed significantly higher values of flavonol/anthocyanin than shallot accessions with the formulas of Y=0.330+19.109X (R=0.771) and Y=1.566+24.832 X (R=0.814) for shallot and A. x wakegi, respectively, where Y is flavonol content and X is anthocyanin content
