Objective: To evaluate the hepatic and renal protective potential of coriander seeds and leaves using animal feed model. Methods: Coriander seeds-and leaves-based sauces were administrated to normal(Study Ⅰ) and carbon tetrachloride(2 mL/kg B.W.)-induced hepatotoxic rabbits(Study Ⅱ). Hepatic and renal biomarkers like aspartate aminotransferase,alanine aminotransferase. alkaline phosphatase, superoxide dismutase and catalase were measured. Results: Coriander leaves-based sauce exerted more decline(P<0.05) in serum aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase levels in the study Ⅱ as 18.32%. 19.91% and 21.24%, respectively. While, hepatic superoxide dismutase and catalase levels were raised significantly(P<0.05) in both studies. Renal parameters also depicted positive impact by the provision of developed sauces. Conclusions: Coriander seeds and leaves based sauces are effective in alleviating the hepato/renal toxicity. The hepatoprotective effect of coriander leaves is more pronounced as compared to coriander seeds.
