In this study, 17 kinds of polyphenols and 5 kinds of anthocyanins were analyzed to compare the contents of polyphenols and anthocyanins in 76 colored agricultural products. A total of 17 polyphenols were analyzed simultaneously by 9 phenolic acids (gallic acid, protocatechuic acid, chlorogenic acid, vanillic acid, caffeic acid, syringic acid, p-coumaric acid, t-ferulic acid, t-cinnamic acid) and 8 flavonoids ((+)catechin, syringic aldehyde, rutin, epicatechin gallate, naringin, luteolin, naringenin, kaempferol) and 5 anthocyanins (delphinidin-3-glucoside, delphinidin- 3-rutinoside, cyanidin-3-galactoside, cyanidin-3-glucoside, cyanidin-3-arabinoside) were simultaneously analyzed. The total content of 17 polyphenols was determined as seoritae 255.1 ± 7.5 μg/g, seomoktae 275.8 ± 5.3 μg/g, black rice 78.5 ± 4.6 μg/g, black sesame 75.8 ± 3.2 μg/g, blueberry 143.3 ± 5.5 μg/g, aronia 195.2 ± 4.9 μg/g and blackcurrent 131.6 ± 3.2 μg/g, the highest content was found in the order of seomoktae > seoritae > aronia > blueberry > blackcurrant > black rice > black sesame. The total content of 5 anthocyanins was determined as seoritae 82.4 ± 17.2 μg/g, seomoktae 95.2 ± 6.1 μg/g, black rice 74.1 ± 9.7 μg/g, black sesame were not detected, blueberry 110.8 ± 1.9 μg/g, aronia 218.9 ± 6.1 μg/g and blackcurrent 209.7 ± 4.0 μg/g, the highest content was found in the order of aronia > blackcurrant > blueberry > seomoktae > seoritae > black rice. These results indicated that seomoktae and aronia possessed the high level of functional components and further study will be needed to develop high value-added foods based on the colored agricultural products.
