The protective effects of total saponins from Rosa laevigata Michx fruit (RLTS) in high-fat diet (HFD)-induced rats were investigated. The results showed that oral administration of RLTS attenuated hepatic steatosis, significantly reduced the levels of body weight, alanine transaminase, aspartate transaminase, total cholesterol, total triglyceride, free fatty acids, low density lipoprotein, blood glucose, insulin and malondialdehyde, and increased high density lipoprotein and glutathione levels compared with the model group. Further investigations showed that RLTS affected fatty acid synthesis, fatty acidβ-oxidation, fatty acid ω-oxidation, total cholesterol and triglyceride metabolism and synthesis. Moreover, the extract obviously suppressed HFD-induced oxidative stress and inflammation. These results suggest that RLTS should be developed to be one functional food or health product against non-alcoholic fatty liver disease (NAFLD) in the future.
