The current study was planned to examine the nephroprotective effect of the crude extract and its various fractions of Viola serpense Wall against paracetamol-induced toxicity in rabbits. The serum creatinine levels of all fractions, as well as the crude extract, were found to have a greater effect. The effect on urine urea by the n-hexane, ethyl acetate, n-butanol and aqueous fraction in high doses (300 mg/kg b.wt.) and crude extract and chloroform in low doses (150 mg/kg bwts.) were comparatively more effective and comparable to silymarin. The creatinine clearance of the fractions except for chloroform, aqueous at 300 mg/kg and the hydro-methanolic extracts at both doses were highly significant. The histological structures of kidneys in crude extract and chloroform-treated groups showed more improvement at the lower doses. The fractions n-hexane, ethyl acetate and n-butanolic exhibited an inverse dose relationship in the histology of the kidney. However, the aqueous fraction showed a dose-dependent nephroprotective effect. Finally, the crude extract and fractions significantly improved paracetamol-induced nephrotoxicity in rabbits.
