Objective: To study the effects of total alkaloids of Rubus alceaefolius( RAP) on non-alcoholic fatty liver disease (NAFLD) rats and explore its possible mechanisms. Method: Sixty SD rats were randomly divided into six groups: control group, model group, compound methionine and choline bitartrate tablets(CMCB) group and three RAP groups treated respectively with low, middle and high dose of RAP. The NAFLD model was induced by feeding fat-rich food. NAFLD rats were administrated with 0.35 g· kg -1 CMCB and 0.36, 0.72, 1.44 g·kg -1 RAP for 4 weeks respectively. The weight index of liver was measured. Hepatic histological changes were observed. The concentration in serum of aspartate amino transferase (AST), alanine amino tranferase (ALT), tumor necrosis factor-α (TNF-α) and interleukin-6(IL-6) were determined. The mRNA expressions of SOD, MDA, TNF-α and IL-6 in hepatic tissue were detected. Result: Compared with the model group, degree of steatosis of hepatic lobule was improved, the weight index of liver was decreased, serum levels of ALT, AST, TNF-α and IL-6 were significantly lower in the high and middle dose RAP group (P <0.05 or P <0.01). The levels of SOD and MDA in hepatic tissue were lower in the high dose RAP group (P <0.05). The mRNA expressions of TNF-α and IL-6 in hepatic tissue were decreased (P <0.05 or P <0.01). Conclusion: RAP can protect liver in experimental NAFLD, and its possible mechanisms may be concerned with clearing the oxygen free radical, reducing the product of lipid peroxidation, inhibiting the release of inflammatory cytokines and reducing nflammatory response.
