Abstract:Experiments have shown that the root of Polygonum multiflorum exhibits inhibitory effect on triglyceride(TG)aceumlation in the liver of mice induced by CCl4, cortisone acetate and thioaeetamide(TAA). Its processed products(Ⅰ, Ⅱ)were found to be effective in lowering the accumulated TG induced by cortisone acetate. The root of Polygonum multiflorum and its processed products also reduced the enlargement of liver by CCl4.
