Anthocyanins, wanda kuma aka sani da anthocyanins, sune flavonoids. Wani nau'i ne na launi na halitta mai narkewa da ruwa wanda ya wanzu a cikin tsire-tsire a yanayi. An samo shi daga hydrolysis na anthocyanins kuma yana samuwa a cikin 'ya'yan itatuwa da kayan marmari da yawa, irin su blueberries, cherries, strawberries, inabi, black currants, bilberries, da dai sauransu, a cikin vacuoles na tsire-tsire. A ƙarƙashin yanayi daban-daban na pH, anthocyanins suna sa tsire-tsire su nuna launuka masu launi, ruwan tantanin halitta acidic ne da ja, kuma ruwan tantanin halitta shine alkaline da shuɗi. Duk anthocyanins a cikin yanayinsu na halitta suna wanzu a cikin nau'in glycosides, wanda ake kira anthocyanins, kuma anthocyanins kaɗan ne masu kyauta. Ana amfani dashi musamman wajen canza launin abinci, kuma ana iya amfani dashi a cikin rini, magani, kayan kwalliya da sauransu. Anthocyanins ana samun su a cikin tsire-tsire, kuma akwai fiye da 300 daban-daban anthocyanins a cikin yanayi.

Dukansu proanthocyanidins da anthocyanins abubuwa ne masu ƙarfi, amma akwai bambance-bambance a bayyane a tsakanin su, galibi dangane da launi, tsarin sinadarai, tushe da aiki.

1. Launi: Proanthocyanidins ba su da launi kuma ana iya canza su zuwa abubuwa masu launi yayin sarrafa abinci da sarrafawa. Anthocyanins pigments ne masu narkewa da ruwa kuma suna ɗaya daga cikin tushen 'ya'yan itace da launin furanni.

2. Tsarin sinadaran: Procyanidins sune mahaɗan polyphenolic, yayin da anthocyanins sune flavonoids. Dalilin kamanni a cikin sunayen biyu shine ana iya samar da anthocyanins ta hanyar dumama procyanidins a yanayin zafi mai zafi a cikin matsakaiciyar acidic.

3. Tushen: Ana samun Proanthocyanidins a cikin nau'ikan nau'ikan tsire-tsire, fatun, da tsaba, gami da haushin Pine, tsaba inabi, haushin kirfa, da sauransu. Anthocyanins galibi suna fitowa ne daga furanni, ganye, da 'ya'yan itatuwa na shuke-shuke. 'Ya'yan itãcen marmari da kayan lambu masu ɗauke da anthocyanins sun haɗa da blueberries, inabi, eggplants, da dai sauransu;
