Ten pigmented potato cultivars native to China were investigated for an evaluation of differences in total anthocyanin content (TAC), composition of individual anthocyanidins, total phenolic content (TPC) and antioxidant activity (AA) between peel and flesh of the tubers. On average, TAC, TPC and AA in the peel were 15.34 times, 7.28 times and 5.75 times higher than in the flesh, respectively. High positive correlations between TAC, TPC and AA were observed. Types and contents of anthocyanidins in the peel were more than in the corresponding flesh, but they had the same dominant anthocyanidins. Results showed peel of pigmented potato tuber can be used as an important source material in production of natural pigments and natural antioxidants.
