Tetrahydroberberine (THB) belongs to the alkaloid of tetrahydroisoquinoline, which is derived from the roots of Corydalis yanhusuo and can also be hydrogenated from berberine. THB has a variety of significant biological activities compared to berberine. It is reported that THB has the effects of anti-hypertension, anti-arrhythmia, anti-fibrillation and against acute myocardial infarction, and also can treat and protect the injury of ischemic and reperfusion.
