However, it is not clear whether anthocyanins can significantly contribute to scavenging of free radicals produced through metabolic processes in leaves, since they are located in the vacuole and, thus, spatially separated from metabolic reactive oxygen species. In addition to their role as light-attenuators, anthocyanins also act as powerful antioxidants. The red coloration of leaves has been proposed to possibly camouflage leaves from herbivores blind to red wavelengths, or signal unpalatability, since anthocyanin synthesis often coincides with synthesis of unpalatable phenolic compounds. This has been shown to occur in red juvenile leaves, autumn leaves, and broad-leaf evergreen leaves that turn red during the winter. In photosynthetic tissues (such as leaves and sometimes stems), anthocyanins have been shown to act as a "sunscreen", protecting cells from high-light damage by absorbing blue-green and ultraviolet light, thereby protecting the tissues from photoinhibition, or high-light stress. In fruits, the colorful skins also attract the attention of animals, which may eat the fruits and disperse the seeds. ANTHOCYANIN Function In flowers, bright-reds and -purples are adaptive for attracting pollinators.
Anthocyanin are derivatives of anthocyanidins, which include pendant sugars. Anthocyanin occur in all tissues of higher plants, including leaves, stems, roots, flowers, and fruits.Īnthoxanthin are clear, white to yellow counterparts of anthocyanin occurring in plants. ANTHOCYANIN belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway pioneer herb ANTHOCYANIN are odorless and nearly flavorless, contributing to taste as a moderately astringent sensation. (Anthocyanins ,also anthocyans) are water-soluble vacuolar pigments that may appear red, purple, or blue depending on the pH. The color of solution can`t fade under light for a long time, and also has good resistance to high temperature in an acidic medium. The solution color becomes blue & green, and is unstable when PH is above 6. When PH is below 3, the color is purple red, the color is pink red when PH is between 4~6, and the colourity is ideal stability. The color of water solution changes when PH is different. It can be dissolved in water & alcohol, acetic acid, propylene glycol solution easily, but not in oil. Red Cabbage Color power is deep red, liquid is brown purple.
