Antioxidant and hepatoprotective potentials of curcuminoid isolates from turmeric ( Curcuma longa ) rhizome on CCl 4 -induced hepatic damage in Wistar rats

摘要

The present study examined the protective effects of curcuminoid isolates from Curcuma longa against carbon tetrachloride (CCL 4 )-induced hepatic injury in rats. The hepatoprotective effect of the crude extract (150, 300 and 600?mg/kg bw) and curcuminoids (75, 150 and 300?mg bw) was evident by significant increases in the serum antioxidative defence capacities (super oxide dismutase, reduced glutathione, catalase) and reduction in biomarker enzymes of liver integrity (aspartate transaminase, alanine transaminase and alkaline phosphatase) in comparison to the results obtained in the CCL 4 -untreated animals. Some of these parameters were completely restored by pre-treatments with curcuminoids. Similarly, the curcuminoids increases the concentrations of total proteins, albumins and ameliorated histological changes observed in CCL 4 injured rats. Therefore, curcuminoid could be considered a novel candidate for the development of new drug against liver diseases.
