Hepatoprotective Effects of Extract of Helicteres hirsuta Lour. on Liver Fibrosis Induced by Carbon Tetrachloride in Rats

Abstract

Helicteres hirsuta Lour. is a traditional Vietnamese medicine for treating chronic liver diseases such as cirrhosis and liver cancer. Many in vitro and in vivo experiments have demonstrated that the extracts and isolated compounds from H. hirsuta have diverse pharmacological activities, including antioxidant, anti-inflammatory, and anti-cancer effects. However, the hepatoprotective effects have not been reported until now. Therefore, the methanolic and ethanolic extracts of the aerial part of the H. hirsuta L. (HHM and HHE-1/1) were examined on liver fibrosis induced by carbon tetrachloride (CCl₄) in rats for the first time. The results revealed that all the livers of the model group had stage F4 cirrhosis; the group that received silymarin, and HHM and HHE-1/1 had milder liver damage cirrhosis stage F1-F2 which implies that the methanolic and ethanolic extracts of H. hirsute have a definite advantage in the development of food or oral medications for hepatoprotective activity.
