The characteristic anthocyanin, vitamin C, dietary fiber and sucrose contents of new types of colored potatoes were studied. The total dietary fiber level in the violet, red and yellow potatoes w[ere 0.75, 0.66 and 0.85o%, respectively. The total vitamin C contents of the violet, red and yellow potatoes were 25.3, 14.l and 31.5mg/100 g, respectively, while the anthocyanin contents of the violet, red and yellow potatoes were 142,148 and 17 mg/100 g, respectively. The main anthocyanin structures in the violet and red potatoes were determined to be petanin and pelanin by FAB-M S and ^1 H-NM R analysis. The red potato anthocyanin was very stable to heat and UV irradiation. Sucrose in the red and yellow potatoes increased during low-temperature storage.
