Berberine extract powder is also called berberine. A common isoquinoline alkaloid, molecular formula C20H18NO4. It exists in many plants belonging to ten genera in four families, including Berberidaceae. First obtained from Xanthoxylonclava bark in 1826 by M.-E. Chavallier and G. Pertain. Berberine is a quaternary ammonium alkaloid. Yellow needle-like crystals can be precipitated from ether; melting point is 145°C; soluble in water, insoluble in benzene, ether and chloroform. The solubility of its salts in water is relatively small, such as 1:500 for hydrochloride and 1:30 for sulfate.
