Acylated anthocyanins from organic purple-fleshed sweet potato (Ipomoea batatas (L.) Lam) produced in Brazil

Acylated anthocyanins from a purple-fleshed sweet potato (PFSP), obtained by organic cultivation in Brazil, were characterized after separation high performance liquid chromatography-diode array detector (HPLC-PDA). These manually collected at the output, concentrated and injected into resolution mass spectrometer (ESI-QTOF-MS2). Twenty-two acylated detected. Among them, sixteen had been reported literature six, derived peonidin for first time roots this study. compounds showed molecular ions with accurate mass/charge ratios (m/z) of 909.2081, 961.3010, 961.2571, 963.3345, 1123.2932 1179.3862. Although PFSP have already extensively studied, variety studied work is probably genetically different all varieties cultivars researched, which would explain why these not observed previously varieties.
