DL-Tetrahydroberberine is racemic form that hydrided from natural Berberine. It contains two optical isomers. Currently, severals of domestic and international research institutions worked together for many years for finding a kind of antiarrhythmic drug that is hydrogenated berberine as the precursors.
A kind of antiarrhythmic drug derived from Canadine with proprietary intellectual property rights will be used for clinical purposes soon.
The products derived from the active ingredients of natural plant Coptis chinensis Franch, Phellodendron amurense Rupr, Corydats yabhusuo W.T. Wang and Berberis julianae Schneid..
