Hepatoprotective effect of Crossostephium chinensis (L.) Makino in rats

Am J Chin Med. 2011;39(3):503-21. doi: 10.1142/S0192415X11008993.

Abstract

The hepatoprotective potential of Crossostephium chinensis (L.) Makino water extract (CCW) on carbon tetrachloride (CCl(4)) induced liver damage was evaluated in preventive and curative rat models. Not only were indicators of hepatic damage including GPT, GOT, lipid peroxides and TBARS were examined, the activities of antioxidant enzymes (SOD, CAT, GPx) and GSH were examined as well. The results showed that CCW (0.1, 0.5 and 1.0 g/kg) significantly reduced the elevated levels of GPT and GOT by CCl(4) administration (p < 0.05). TBARS level was dramatically reduced, and SOD, CAT, GPx and GSH activities were significantly increased. In addition, CCW decreased NO production and TNF-α activation in CCl(4)-treated rats. Therefore, we speculate that CCW protects against acute liver damage through its radical scavenging ability. CCW inhibited the expression of MMP-9 protein, indicating that MMP-9 played an important role in the development of CCl(4)-induced chronic liver damage in rats. In LC-MS-MS analysis, the chromatograms of CCW with good hepatoprotective activities were established. Scopoletin may be an important bioactive compound in CCW.
