Objectives : We try to compare the efficacy of six herbal medicines, Rhizoma Alismatis (RA), Fructus Crataegi (FC), Fructus Lycii (FL), Radix Curcumae (RC), Radix Salviae Miltiorrhizae (RSM), and Herba Artemisiae Scopariae (HAS), constituting KHchunggan-tang which was previously proven to be hepatoprotective on non-alcoholic fatty liver disease with the combined properties in cellular steatosis, ROS production, and cytoprotection. Methods : HepG2 cells were pretreated with aqueous extracts of the six herb medicines at concentrations of 1, 10, 50 and 100 μg/ml each, and treated with 0.5 mM palmitate consecutively. After 21 hrs, cell viability was assessed using MTT assay, and the percentage of cells with sub-G1 DNA content was measured using fluorescence-activated cell sorting after propidium iodide staining. Results : The first three extracts, RA, FC, and FL restored cell viability reduced by palmitate in MTT assay, and RA, FC, FL and RC inhibited palmitate-induced apoptosis in sub-G1 analysis. FL showed relatively weak potential only at tested maximal dose, and RA showed the most higher efficacy on this experimental cellular model of nonalcoholic fatty liver disease. Conclusions : According to this comparative experiment, Rhizoma Alismatis seems to have the most powerful potential among above six herbs constituting KHchunggan-tang, and consecutive further study seems to be required for more standardized and effective clinical application of KHchunggan-tang for treatment of non-alcoholic fatty liver disease.
