Anthocyanidins are common plant pigments, the aglycones of anthocyanins. They are based on the flavylium cation, [1] an oxonium ion, with various groups substituted for its hydrogen atoms. They generally change color from red through purple, blue, and bluish green as a function of pH.

2023年10月6日 · Anthocyanins are a group of antioxidants found in red, purple, and blue fruits and vegetables (1). They belong to the flavonoid family — the same family as the antioxidants found in wine,...

2023年9月26日 · Anthocyanidin is a reddish-purple (magenta) pigment and is found in berries and other red-colored vegetables, like sweet potatoes and purple corn. Anthocyanidins and anthocyanins are used as natural dyes and food-coloring agents.

Anthocyanins (from Ancient Greek ἄνθος (ánthos) 'flower' and κυάνεος / κυανοῦς (kuáneos/kuanoûs) 'dark blue'), also called anthocyans, are water-soluble vacuolar pigments that, depending on their pH, may appear red, purple, blue, or black.

Scientific studies, such as cell culture studies, animal models, and human clinical trials, show that anthocyanidins and anthocyanins possess antioxidative and antimicrobial activities, improve visual and neurological health, and protect against various non-communicable diseases.

Anthocyanins are glucosides of the anthocyanidins, flavonoid derivatives produced via the phenylpropanoid pathway. They are present in all tissues of higher plants, including leaves, stems, roots, flowers, and fruits. The six predominant anthocyanidins found in foods are cyanidin, delphinidin, pelargonidin, peonidin, petunidin, and malvidin [6, 7].

Anthocyanin and anthocyanidins are water-soluble heteroaromatic compounds that have three rings connected to each other in their bodies. The basic chromophore structure of these compounds is 2-phenyl-benzopyrylium (Fig. 9). Anthocyanins and anthocyanidins have diverse chemical structures that create great reactivity and color diversity in them.

The most well-known anthocyanins are cyanidin 3- O -glucoside and cyanidin 3- O -rutinoside. They are widespread in nature, being present in considerable amounts in red fruits and red vegetables.

2022年6月2日 · Anthocyanins (an-tho-SY-uh-nins) are a group of deep red, purple and blue pigments found in plants. They’re part of a larger category of plant-based chemicals called flavonoids. Flavonoids are abundant in all parts of plants: …

Proanthocyanidins are chemical compounds. They give the fruit or flowers of many plants their red, blue, or purple colors. They were first studied for their importance as plant pigments. These compounds have anti-inflammatory properties and may help prevent cancer. Proanthocyanidins are in a group of compounds called polyphenols.
