Berberonic acid (pyridine-2,4,5-tricarboxylic acid) is an organic compound that belongs to the heterocycles (more precisely the heteroaromatics). It belongs to the group of pyridinetricarboxylic acids and consists of a pyridine ring which carries three carboxy groups in the 2-, 4- and 5-positions. The name is derived from berberine.

Preparation

Berberonic acid is obtained in the oxidation of berberine with nitric acid.^[1] It can also be derived by oxidative degradation of monascaminone with potassium permanganate.^[2]
