The genus Aronia has been used in American traditional medicine with health benefits such as antidiabetic, cardioprotective, and anti-mutagenic. Aronia melanocarpa, also known as black chokeberry, is one of three species belonging to the Aronia genus. A. melanocarpa is rich in not only anthocyanins, proanthocyanidins, and flavonoids but also many anti-oxidant vitamins, including vitamin C, vitamin A, and vitamin E. Its excellent anti-oxidant activity is attributed to a high content of polyphenol compounds.
