Anthocyanin glycosyl acylation commonly refers to the phenomenon in which the hydroxyl groups of anthocyanin glycosyls are esterified by aliphatic or aromatic acids, which is synthetically represented by the acylation sites as well as the types and numbers of acyl groups.

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. Anthocyanins are flavonoid compounds responsible for red/purple colours in the leaves, fruit and flowers of many plant species. Acylated anthocyanins are more stable than monomeric anthocyanins, but little is known about their physiological effects.
Download. 2019-03-01 The activity of acylated anthocyanins mostly depended on the activity of intramolecular acyl units (caffeic acid > ferulic acid > p -coumaric acid). However, the activity was highly affected by the binding site of intramolecular acyl units even if anthocyanins have common acyl units. The amount of anthocyanins in the food grade crude extract from 100 g of potato (fresh weight) was 37.02 mg and the amount of purified anthocyanins present in the extract was 26.34 mg. The main anthocyanins identified were the rutinoside and glucosides of peonidin, petunidin, malvidin, and cyanidin acylated to p-coumaroyl, and feruloyl. 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.Anthocyanin characterization of red cabbage is not a new topic, but the predominant anthocyanins have been co‐eluted using high performance liquid chromatography (HPLC) because of … New Acylated Anthocyanins and Other Flavonoids from the Red Flowers of Clematis Cultivars.

Abstract Three anthocyanins have been isolated from the leaves of the water lily, Nymphaea × marliacea . Even though the lability of the two major anthocyanins was high, especially the linkage between the acetic acid and the galactose moieties, it was possible by means of homo- and heteronuclear two-dimensional NMR techniques and electrospray mass spectrometry to give the full structures of The profile of AVI-bound anthocyanins showed an increase in acylated anthocyanins in both lines of approx.

Anthocyanins are present in fruits and berries as non-acylated glycosides of anthocyanidins, whereas acylated anthocyanins are found in some other foods such as purple potatoes, cabbages, and corns. Due to the different molecular structures, acylated anthocyanins differ from non-acylated anthocyanins in stability, solubility, and bioavailability.
