Anthraquinone CAS 84-65-1

Anthraquinone refers to anthracene compounds with carbonyl groups at C9 and C10 positions. It is a polycyclic organic compound, also known as 9,10-anthraquinone and 9,10-anthraquinone. In 1835, Laurent used nitric acid to oxidize anthracene and first produced anthraquinone.

Anthraquinone derivatives are all colored and widely exist in nature. Most anthraquinone compounds in natural products contain hydroxyl groups, often existing in a free state or in a state of glycosides combined with sugars. Free anthraquinones and their glycosides often coexist in the same plant. Many laxative Chinese medicines such as rhubarb, aloe, senna leaves, and rhamnaceous fruit contain laxative anthraquinone derivatives. Some natural anthraquinone compounds can be used as dyes, such as alizarin and hydroxyalizarin contained in madder. Anthraquinone components are often found in higher plants of Polygonaceae, Leguminosae, Rubiaceae, and Rhamnaceae, as well as metabolites of lower plants of lichens and fungi.
