Coptis chinensis is a famous Chinese medicine, which is listed as the top grade in Shennong Herbal Classic. The taste of rhizome is bitter, and the bitterness lies in the types of alkaloids it contains, mainly berberine, followed by methylcoptisine and amitriptyline. Berberine is the hydrochloride of berberine, which has inhibitory effects on Shigella dysenteriae, Staphylococcus aureus, Salmonella typhi, Vibrio cholerae and other bacteria. Usually made into tablets or injections, it has obvious curative effect on bacillary dysentery. Coptis chinensis has high living conditions, slow growth and low yield, which is difficult to meet the market demand. It was found that the roots and stems of many Berberidaceae Berberis plants also contain a lot of berberine, such as Cotinus coggygria, porcupine thorn, Berberis Anhui, Berberis Lushan and so on. They can extract berberine instead of Rhizoma Coptidis to make berberine.
