Palmatine (PAL) is one of the main alkaloids in Coptis chinensis. The present aim was to investigate the hypolipidemic effect and mechanism of palmatine in hamsters fed with high‐fat diet (HFD). PAL treatment decreased serum total cholesterol (TC), triglyceride (TG), and low‐density lipoprotein cholesterol (LDL‐C) levels, as well as increased fecal excretion of TC and total bile acids (TBA) in hyperlipidemic...
Current work was conducted to evaluate the cholesterol-lowering effect of coptisine extracted from Rhizomacoptidis in Syrian golden hamsters. The safety results indicated that coptisine was a safe and low-toxic compound. Coptisine showed a beneficial effect in the abnormal serum lipid levels induced by a high-fat and high-cholesterol diet (HFHC): at a concentration of 70.05 mg/kg, coptisine significantly...
Current work was conducted to evaluate the safety and antihypercholesterolemic activity of jatrorrhizine extracted from Rhizoma Coptidis (RC) and its potential mechanism on regulating cholesterol metabolism. It was found that the LD 50 of jatrorrhizine in mice was more than 5500mg/kg and there were no influences on clinical signs, organ weight changes, urinalysis and hematological parameters,...
