The identification and quantitation of the anthocyanins in 12 purple-fleshed sweet potato (PFSP) cultivars (‘Jihei 1’, ‘Xuzi 3’, ‘Xuzi 6’, ‘Zhezi 4’, ‘Ningzi 1’, ‘Ningzi 2’, ‘Ningzi 3’, ‘Ning 2-2’, ‘Ning 6-8’, ‘Guangzi 1’, ‘Ziluolan’, and ‘Qinzi 1’) in China were carried out using a combination of ultraperformance liquid chromatography–photodiode array (UPLC-PDA), quadrupole-time-of-flight mass spectrometry (QTOF-MS), and tandem mass spectrometry (MS/MS) analyses. Thirteen acylated anthocyanins were tentatively characterized, including two new PFSP anthocyanins, cyanidin 3-caffeoyl-vanilloyl sophoroside-5-glucoside and peonidin 3-caffeoyl-vanilloyl sophoroside-5-glucoside. The quantitative analyses of these anthocyanins were conducted using cyanidin 3-O-glucoside as a standard. The total anthocyanin content of the PFSPs depended on the cultivar. The five PFSP cultivars with the highest content of anthocyanins were ‘Jihei 1’, ‘Xuzi 3’, ‘Zhezi 4’, ‘Ziluolan’, and ‘Qinzi 1’. This is the first report of the ‘Ningzi 2’, ‘Ningzi 3’, and ‘Ning 2-2’ PFSP cultivars containing only diacylated anthocyanins and of the ‘Xuzi 6’ cultivar containing single anthocyanidin-based anthocyanins.
