Acylated anthocyanins

In this study, high molecular weight acylated monomeric anthocyanins were isolated from purple sweet potato (Ipomoea batatas L. cultivar Eshu No. 8) via the combination of column chromatography and semi‐preparative HPLC technology and identified mainly by ultra‐high‐performance liquid chromatography quadrupole time‐of‐flight tandem mass spectrometry/mass spectrometry (UPLC‐QTOF‐MS/MS) and 1 H and 13 C nuclear magnetic resonance (NMR). Four new acylated anthocyanins with three known pigments were isolated from the rhizome of the Chinese red radish (Raphanus sativus cv. Beijing hong xin), and their structures were determined. A grapevine anthocyanin acyltransferase, transcriptionally regulated by VvMYBA, can produce most acylated anthocyanins present in grape skins.

While only a minor component within the RCA mixture, this unique compound warranted further investigation to understand the structural factors conferring its desirable spectral properties. Additionally, this method provides a good reference for the separation of acylated anthocyanins in fruits and vegetables. Practical Applications Red cabbage ( Brassica oleracea L. Var. Capiata L.) is a fresh edible vegetable abundant in acylated anthocyanins with high antioxidant properties, and is a promising resource for the functional food industry.
