The Metabolic Fate and Bioactivity of Anthocyanins in Humans
Anthocyanins, the class of flavonoid responsible for giving a red hue to many berries, have been associated with a decreased risk of cardiovascular disease. However, numerous intervention studies feeding anthocyanin-rich foods report limited (<1%) bioavailability of the parent anthocyanins in vivo. …

Side chain decoration of Anthocyanins; Mechanisms and Effects On functionality
Anthocyanins are plant pigments offering a range of colours to fruits and flowers. Many properties of anthocyanins are influenced by the degree and type of side chain modifications. Though much is known about the biosynthesis of anthocyanins and the enzymes involved in side-chain decoration, there …

Cellular uptake and actions of bilberry anthocyanins in retinal pigment epithelial cells
… stress and die via the process of apoptosis. Anthocyanins from fruits and berries, such as bilberry (Vaccinium myrtillus), possess significant antioxidant activity in vitro and have been used in "traditional medicine" to treat AMD. It is not clear whether intracellular concentrations of …

Characterization of antioxidant activities from fruits rich in delphinidin or malvidin anthocyanins
Anthocyanins have been shown to possess specific antioxidant capacities, which may provide an underlying protective effect against many chronic diseases . Although the antioxidant capacity of anthocyanins has been well established, less is known about the extent to which specific anthocyanin …

Bioaccessibility and metabolism of anthocyanins: effects of fermentation, encapsulation, and microbiota interactions
Anthocyanins have been widely studied for their health benefits; however, these compounds exhibit low bioaccessibility and bioavailability due to degradation and limited absorption in the gastrointestinal tract, which may restrict their effects. Therefore, innovative strategies to enhance the …

Evaluation and modification of processing techniques for recovery of anthocyanins from colored corn
… natural alternatives of synthetic dyes. Anthocyanins can be used as a replacement of synthetic FD&C Red 40 dye. However, their recovery from conventional sources is uneconomical due to higher inputs and lower economic value of the processing residues. The potential of using colored corn …

Biological activity of anthocyanins and their phenolic degradation products and metabolites in human vascular endothelial cells
… indicate significant vasoprotective activity of anthocyanins. However, few studies have investigated the activity of anthocyanin degradation products and metabolites which are likely to mediate bioactivity in vivo. The present thesis therefore examined the vascular bioactivity in vitro of …

Neuroprotective Effects of Anthocyanins on Neuronal Death Induced by Inhibition of Bcl-2 and Oxidative Stress
… effects of a novel class of nutraceuticals, anthocyanins, against MOS-induced death in primary cultures of rat cerebellar granule neurons (CGNs). Anthocyanins are natural antioxidants whose neuroprotective potential has yet to be examined in detail. Kuromanin and callistephin are anthocyanins …

Inhibitory potential of anthocyanins and anthocyanin-rich extracts on colorectal cancer progression through apoptosis, angiogenesis, and immune response effects
… to metastasis could increase survival rates. Anthocyanins, a subcategory of flavonoids, are natural red, purple, and blue pigments in a variety of plants consumed in a healthy diet. Many colorful fruits, vegetables, cereals, and legumes are rich in anthocyanins. The reported health benefits of …

Impacts of Water, Extraction Procedure and Origin on Anthocyanins and Volatile Compositions of Hibiscus Extracts and Freeze-Dried Hibiscus
… of water, extraction procedure and origin on the anthocyanins of hibiscus extracts and secondly, to examine the impacts of freeze-drying on the anthocyanins and the volatiles compositions of hibiscus extracts. For the first experiment, a 2x3 factorial design was used with hibiscus calyces from …

The Neuroprotective and Therapeutic Effects of Anthocyanins and Their Metabolites In Vitro and in a Mouse Model of Amyotrophic Lateral Sclerosis
<p>Anthocyanins, a unique class of flavonoid compounds, have recently come to the forefront of investigative research aimed at evaluating the potential applications of natural products to human health. Evidence demonstrating the beneficial effects of anthocyanin consumption has been reported for a …

Engineering of polyphenol metabolism in tomatoes to enhance anti-cancer activities
Anthocyanins are polyphenolic plant pigments that are responsible for much of the attractive colour displays found in many flowers, fruit and vegetables. Anthocyanins are divided into different classes based on the number of hydroxyl groups on their phenyl B-ring and subsequent side chain …

Anthocyanins and proanthocyanidins from blueberry and blackberry fermented beverages to reduce inflammation and type-2 diabetes: a comprehensive in vitro and in vivo evaluation
… decreased risk for type-2 diabetes, specifically anthocyanins (ANC) and proanthocyanidins (PAC), polymerized forms of ANC and other phenolics. Fermentation is a feasible way to increase phenolic content of berry juice products, and fermented products may be more bioactive than their unfermented …

The Photoprotective Role of Anthocyanin Pigments in Leaf Tissues
Anthocyanins are vacuolar pigments most commonly responsible for red to purple coloration in plant tissues. Because they absorb strongly in the blue-green waveband, anthocyanins effectively reduce internal light within the leaf, which may be beneficial under high-light stress conditions. However, …

The transcriptional regulation and health benefits of anthocyanin in Actinidia (kiwifruit) species
Anthocyanins are plant secondary metabolites that colour flowers and fruit red, purple, and blue. They belong to the flavonoid class. The accumulation of anthocyanin confers protection against photooxidative effects and attracts pollinators and seed dispersers. Anthocyanins in fruit act as an …

Characterisation of phenolic antioxidants in fruits and vegetables : bioavailability of raspberry phenolics in humans and rats
… in blackcurrants and blueberries were the anthocyanins. Blackcurrants contained large amounts of anthocyanins (5446 nmol/g) and vitamin C (2328 nmol/g) and had the highest AOC of the five berries. Blueberries were the second highest with anthocyanins levels of 4908 nmol/g but the sample …

Encapsulation, Color Stability, and Distribution of Anthocyanins from Purple Corn (Zea mays L.), Blueberry (Vaccinium sp.), and Red Radish (Raphanus sativus) in a Cold-Setting Pectin-Alginate Gel.
Anthocyanins are a broad class of water soluble pigments found in a wide array of plants. They are responsible for a variety of the attractive colors found in fruits including red, purple, orange, and blue. There use as a natural alternative to synthetic colorants has been investigated extensively …

Aspects of the prevention of light damage during drying and rehydration of the desiccation-tolerant grass Eragrostis nindensis
… pigments (chlorophylls and carotenoids) and of anthocyanins were measured. Electrolyte leakage of drying and rehydrating leaves was monitored to determine the extent of damage to membranes. Quantum efficiency and photosynthetic pigment contents were reduced in both plant§ dehydrated to <2% RWC; …
