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. 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.
Acylated anthocyanins and especially those acylated with aromatic acids are exceptionally resistant to discoloration (Dangles et al., 1993; Cheynier et al., 2006). Grapevine (Vitis vinifera) anthocyanins are the 3-monoglucosides of five anthocyanidins: cyanidin, delphinidin and its methylated derivatives, peonidin, petunidin, and malvidin. anthocyanins. Acylated anthocyanins, instead, provide enhanced structural stability for the otherwise unstable anthocyanins and thus have the potential to increase the use of anthocyanins in food industrial applications. Acylated anthocyanins are commonly found in pigmented vegetables and tubers, such as ACYLATED ANTHOCYANINS AS STABLE, NATURAL FOOD COLORANTS – A REVIEW. Anna Bakowska.

Decreased food intake and body weight gain, and increased lung weight and atherogenic index by feeding the rats on a diet containing paraquat were clearly suppressed by supplementing acylated anthocynins to the paraquat diet.

We evaluated the hemodynamic effects of single intragastric doses of purple carrot (Daucus carota L.) anthocyanin (PCA) and two monomeric anthocyanins, cyanidin 3-O-glycoside (C3G) and de Findings of acylated anthocyanins with increased stability have shown that these pigments may impart desirable color and stability for commercial food products. Examples of suitable acylated anthocyanin sources may be radishes, red potatoes, red cabbage, black carrots, and purple sweet potatoes.
Acylated anthocyanins have shown to be promising alternatives to the use of synthetic dyes in food systems. Depending on anthocyanin chemical structure and pH of food matrix, a wide variety of hues can be achieved. Anthocyanin acylation improves color and pigment stability. Acylated anthocyanins are more stable than monomeric anthocyanins, but little is known about their physiological effects.

Acylated anthocyanins as stable, natural food colorants - a review. Author(s) : Bąkowska-Barczak, A. Author Affiliation : Department of Fruit, Vegetable and Cereals Technology, Agricultural University of Wrocław, ul. Norwida 25, 50-375 Wrocław, Poland. Author Email : annab@star.ar.wroc.pl
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.

2003-06-01 Acylated anthocyanins are more stable than monomeric anthocyanins, but little is known about their physiological effects. We evaluated the hemodynamic effects of single intragastric doses of purple carrot ( Daucus carota L.) anthocyanin (PCA) and two monomeric anthocyanins, cyanidin 3- O -glycoside (C3G) and delphinidin 3- O -ruthenoside (D3R). 2015-04-07 2020-07-01 The finding that anthocyanin pigments containing acyl substituent are incredibly stable opens new opportunities for food producers. The stable acylated anthocyanins are present in large amounts in vegetables such as: red cabbage, black carrot, red radish, red potatoes ABSTRACT: The thermal degradation pathways of acylated and nonacylated anthocyanins from 3 commercial sources have been investigated.
We evaluated the hemodynamic effects of single intragastric doses of purple carrot ( Daucus carota L.) anthocyanin (PCA) and two monomeric anthocyanins, cyanidin 3- O -glycoside (C3G) and delphinidin 3- O -ruthenoside (D3R). By contrast, the acylated anthocyanin solution dissolved in these solvents was unmistakably red. In terms of the antioxidant activity, acylated bilberry anthocyanins demonstrated inferior performance in 2,2-diphenyl-1-picrylhydrazyl (DPPH) clearance but a better inhibition ratio in β-carotene bleaching assay compared with native bilberry anthocyanins. Malvidin-3-O- (6-p-coumaroyl)glucoside p-Coumaroylated anthocyanins are a type of anthocyanins with a p -coumaric acid unit linked with a sugar to an anthocyanidin aglycone. 3- (6- p -Coumaroyl)glucosides are found in grape and wine. Cyanidin-3- O - (di- p -coumarylglucoside)-5-glucoside is found in dark opal basil.
