That anthocyanins may protect leaves in plants facing biotic or abiotic stressors an idea dating back to Pringsheim 1879 is arguably the most widely accepted function for foliar anthocyanins although the mechanism s by which they could mitigate effects of stress remains heatedly debated. Anthocyanins are the largest group of phenolic pigments and the most important group of water-soluble pigments in plants 68 69 101 104 responsible for the red purple and blue colors found in many fruits vegetables cereal grains and flowers being odorless and nearly flavorless and contributing to taste as a moderately astringent sensation.

Anthocyanins are blue red or purple pigments found in plants especially flowers fruits and tubers.
Anthocyanin in plants. These pigments have several functions in the plant and they are also of nutritional interest because they have been linked with nutritional benefits such as cancer prevention. The glycosides of the three non-metylated anthocyanidins delphinidin cyanidin and pelargonidin are the most abundant in nature which represent 80 of leaf pigments 69 in fruits and 50 in flowers. Depending on the pH of the plant.
These include the attraction of pollinators and frugivores as well as the repellence of herbivores and parasites. Anthocyanin major class of red to blue flavonoid pigments that are extensively represented in plants. The most common anthocyanidins in higher plants are.
Earlier these compounds were only known as natural food colorants the stability of which depended on pH light storage temperature and chemical structure. There are more than 600 types of pigments exhibiting color change. A typical anthocyanin pigment appears red in acid violet in neutral and blue in alkaline solution.
Extracts of plant material contain concentrated amounts of the aromatic colouring or functional components of raw material. These anthocyanins are then utilized in antioxidant activities by scavenging excess ROS for their sustainability. In addition to their well-documented beneficial effects on plant physiological processes anthocyanins have also been proposed to function in a diverse array of plantanimal interactions.
Anthocyanins are specialized metabolites of the phenylpropanoid pathway that are widely distributed in the plant kingdom. Anthocyanin can create extracts that provide a more intense flavour than traditionally used dried herbs and ground spices. In these parts they are found predominantly in outer cell layers.
Anthocyanins are water soluble pigments found in many plants. In plants anthocyanins play a role not only in reproduction by attracting pollinators and seed dispersers but also in protection against various abiotic and biotic stresses. Anthocyanins are water-soluble pigments providing certain color for various plant parts especially in edible berries.
In such conditions plants produce anthocyanins after ROS signaling via the transcription of anthocyanin biosynthesis genes. Anthocyanins are water-soluble and are found in the vacuoles of plant cells. In acidic condition anthocyanin appears as red pigment while blue pigment anthocyanin exists in alkaline conditions.
Delphinidin cyanidin petunidin pelargonidin peonidin and malvidin. These glycosylated flavonoids are one of the most important water-soluble pigments in plants and provide the shades of blue purple red and pink to plant organs including leaves petals fruits and seeds Mazza and Miniati 2018. Anthocyanins are a group of polyphenolic pigments that are ubiquitously found in the plant kingdom.
Anatomically anthocyanins are found in the cell vacuole mostly in flowers and fruits stems and roots. Notably anthocyanins have been reported to occur only in the mesophyll layers of other plant species including Muhonia Viburnum and Rhododen- dron 24 and the tropical woody genus Syzygium 33. Shade plants accu- mulate anthocyanins in their lower epidermis perhaps to as- sist in light capture 2627.
Anthocyanins are a class of pigments that occur naturally in plants. These pigments give plants their vibrant colors such as reds and purples. In addition to their well-documented beneficial effects on plant physiological processes anthocyanins have also been proposed to function in a diverse array of plantanimal interactions.
People eat anthocyanins every day and many people have a diet rich in these pigments.
