Anthocyanin Biosynthesis 21421.Pdf Anthocyanin Biosynthesis – https://www.kegg.jp/kegg-bin/highlight_pathway?scale=1.0&map=map00942&keyword=flavonoids Anthocyanidins (aglycones) and anthocyanins (glycosides) are common plant pigments and belong to a structural subclass of flavonoids characterized by a 2- phenylbenzopyrylium unit. They are derived along the flavonoid modification pathways and further separated into three types, pelargonidin, cyanidin, and delphinidin, due to the different number of hydroxyl groups in the phenyl group.

The flavonoids of american cranberry (Vaccinium macrocarpon Alt.) are documented to be beneficial for hu- man health. Among their benefits is a high antioxidant potential, with anthocyanin glycosides being the main contribu- tors. Flavonoid glucose conjugates are reported to be more bioavailable than those with other sugar conjugates. The anthocyanin glycosides of V. macrocarpon fruit are mainly galactosides and arabinosides of the aglycones, cyanidin and peonidin, with less than 8% glucosides. In contrast, the fruit anthocyanins of another cranberry species, V. oxycoccus L. were found to be largely glucosides of cyanidin and peonidin. Interspecific hybrids between these two species were intermediate to the parental species in the proportion of fruit anthocyanin glucosides. About half the progeny (1:1 segregation) in a backcross population (to V. macrocarpon) maintained the relatively high anthocyanin glucoside ratio. In this study, we demonstrate the genetic manipulation of anthocyanin glycosylation in cranberry using interspecific hybridization, resulting in dramatically increased glucose-conjugated anthocyanins. Flavonoids are considered to be secondary metabolites, which The cultivated american cranberry (V. macrocarpon) is recog- have been associated with roles in ultraviolet protection, plant nized for its brilliant red fruit due to an abundance of anthocyanins sexual reproduction, pollinator attraction, symbiotic plant—microbe in the fruit epidermal tissues.

  • 1 Anthocyanin Based Blue Colorants THESIS
    Anthocyanin Based Blue Colorants THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Neda Ahmadiani Graduate Program in Food Science and Nutrition The Ohio State University 2012 Master’s Examination Committee: Dr. M. Monica Giusti, Advisor Dr. Sheryl Barringer Dr. Melvin Pascall 1 Copyrighted by Neda Ahmadiani 2012 2 ABSTRACT Anthocyanins are a group of natural pigments extensively found in nature. Two main functions of these compounds are their ability to elicit different colors and to impart health benefits. Color is an essential part of the identity of foods and can affect the products’ success in the market. The food industry is searching for natural alternatives to the use of synthetic dyes. A particularly difficult challenge has been finding a natural blue that can replace synthetic FD&C Blue colorants. Some anthocyanins, under neutral to alkaline conditions can turn blue; however, the shades and stability of the blue color highly depends on the source. The aim of this study was to identify and increase our understanding of anthocyanin-based blue colorants from edible materials that can closely match the color characteristics of synthetic FD&C Blue colorants. To achieve this objective, anthocyanins from edible materials as well as commercial extracts were evaluated in regards to color and stability under a wide range of pH. Antocyanins from Baby Indian, Italian, and American eggplant, known to be delphinidin derivatives, were extracted. Delphinidin has three hydroxyl groups on its B-ring expected to cause a bathochromic shift and yield a blue hue.

    EFFECT OF SUN EXPOSURE ON THE EVOLUTION AND DISTRIBUTION OF ANTHOCYANINS IN INTERSPECIFIC RED HYBRID WINEGRAPES A Thesis Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Master of Science by Catherine Hope Dadmun August 2020 © 2020 Catherine Hope Dadmun ABSTRACT Interspecific hybrid winegrapes are economically important in areas where environmental pressures inhibit traditional Vitis vinifera production. To clarify the effect of vine microclimate on red hybrid wine color, skin extract anthocyanins were characterized via HPLC for shaded and unshaded fruit from three economically significant cool-climate hybrid cultivars (Vitis spp): Corot noir, Maréchal Foch, and Marquette. Light exposure and berry and air temperature were monitored in Corot noir to represent generalized vine microclimate. Across all cultivars, the samples that underwent the leaf-pulling treatment (exposed samples) did not have significantly different concentrations of total anthocyanins compared to the control (shaded samples). However, certain individual anthocyanins within each cultivar demonstrated different concentrations with the exposure treatment. This work is the first step in defining the evolution of anthocyanin profiles during interspecific hybrid grape ripening to allow cool- climate wine grape growers to optimize viticultural production methods for high-quality red hybrid wines. Keywords: anthocyanin, interspecific hybrid, ripening, sunlight exposure, viticultural practice, leaf removal BIOGRAPHICAL SKETCH Catherine Dadmun joined Anna Katharine Mansfield’s group in the Department of Food Science and Technology at Cornell University in August 2018. She studies grape and wine chemistry, primarily focusing on hybrid Vitis spp. and the chemical color composition of grapes. Beyond academics, Catherine was heavily involved in the Food Science Graduate Student Organization (FSGSO), the Graduate and Professional Women’s Network (GPWomeN), and tutoring students at Beverly J.

The fruit of the American cranberry, Vaccinium macrocarpon Ait., is recognized as having six anthocyanins, composed largely of 3-O-galactosides and 3-O-arabinosides, and to lesser amount (≈6%), 3-O-glucosides of the aglycones cyanidin and peonidin. This study analyzed proportions of these six anthocyanins from >250 accessions of a germplasm collection over harvest dates. Fruit samples from 78 selected accessions, based on the fi rst year analysis, were also analyzed a second year. Principal component analysis identifi ed general negative relationships between the proportions of cyanidin versus peonidin, arabinosides versus glucosides, and galactosides versus arabinosides and glucosides. These relationships were consistent across the 2 years. Most variation in germplasm anthocyanin profi les refl ected variation of cyanidin versus peonidin proportions, with cyanidin to peonidin ratios ranging from 3.6:1 to 0.5:1. Variation for glycosylation profi les was also evident, with galactoside proportions ranging from 64% to 75%, arabinoside proportions ranging from 20% to 33%, and glucoside proportions ranging from 3% to 9%.

  • The Chemical Reactivity of Anthocyanins and Its Consequences in Food Science and Nutrition
    molecules Review The Chemical Reactivity of Anthocyanins and Its Consequences in Food Science and Nutrition Olivier Dangles * ID and Julie-Anne Fenger University of Avignon, INRA, UMR408, 84000 Avignon, France; [email protected] * Correspondence: [email protected]; Tel.: +33-490-144-446 Academic Editors: M. Monica Giusti and Gregory T. Sigurdson Received: 6 July 2018; Accepted: 31 July 2018; Published: 7 August 2018 Abstract: Owing to their specific pyrylium nucleus (C-ring), anthocyanins express a much richer chemical reactivity than the other flavonoid classes. For instance, anthocyanins are weak diacids, hard and soft electrophiles, nucleophiles, prone to developing π-stacking interactions, and bind hard metal ions. They also display the usual chemical properties of polyphenols, such as electron donation and affinity for proteins. In this review, these properties are revisited through a variety of examples and discussed in relation to their consequences in food and in nutrition with an emphasis on the transformations occurring upon storage or thermal treatment and on the catabolism of anthocyanins in humans, which is of critical importance for interpreting their effects on health. Keywords: anthocyanin; flavylium; chemistry; interactions 1. Introduction Anthocyanins are usually represented by their flavylium cation, which is actually the sole chemical species in fairly acidic aqueous solution (pH < 2). Under the pH conditions prevailing in plants, food and in the digestive tract (from pH = 2 to pH = 8), anthocyanins change to a mixture of colored and colorless forms in equilibrium through acid–base, water addition–elimination, and isomerization reactions [1,2]. Each chemical species displays specific characteristics (charge, electronic distribution, planarity, and shape) modulating its reactivity and interactions with plant or food components, such as the other phenolic compounds.
