1. Reduce liver damage: oleanolic acid as a pentacyclic triterpenoids, CCl4-induced acute and chronic liver injury in rats have a significant protective effect. After treatment, the enlarged mitochondria and dilated rough endoplasmic reticulum were restored. Liver cells can also be acute and chronic liver damage caused by balloon degeneration, necrosis and inflammatory response was significantly reduced. Liver triglyceride accumulation decreased, increased glycogen content.  


2. Lower serum alanine aminotransferase activity: oleanolic acid on acute, chronic hepatitis and liver cirrhosis animals were significantly decreased enzyme.  


3. Reduce serum r-globulin, and histological observation of the liver is consistent with the reduction of inflammatory response.


4. Promote the regeneration of liver cells: oleanolic acid can promote the number of rat liver residual mitotic phase was significantly increased, the regeneration of higher than the control group, suggesting a role in promoting cell regeneration.


5. Inhibition of hepatic fibrosis: Oleanolic acid treatment of liver fibrosis in rats, severe and significantly reduced hepatic fibrosis, liver collagen content decreased, suggesting that the role of prevention and treatment of cirrhosis.
