Abstract The nephroprotective effect of standardized aqueous root extract of Vetiveria zizanioides (L.) Nash (Family: Poaceae) was investigated in doxorubicin‐induced (20 mg/kg, ip) experimental nephrotoxicity model of Wistar rats. The freeze‐dried aqueous refluxed (4 hr) root extract of V . zizanioides (25, 50; equivalent human therapeutic dose and 100 mg/kg) was administered separately to nephrotoxic Wistar rats ( n = 6/group). Supplement of V. zizanioides resulted a dose‐dependent reduction in raised serum creatinine, β 2 ‐microglobulin, and blood urea nitrogen and a subsequent increase in serum total protein and albumin in nephrotoxic rats ( p < .05). An attenuation of the doxorubicin‐induced features of renal parenchymal injury was observed on H‐ and E‐stained sections of the kidney tissues. Nootkatone, dehydroaromadendrene, isokhusenic acid, α‐vetivone, and isolongifolene were identified in the methanol extract of V. zizanioides based on the GC‐MS chromatogram analysis. The findings revealed that the supplement of standardized aqueous root extract of V . zizanioides had a significant dose‐dependent nephroprotective activity against doxorubicin‐induced experimental nephrotoxicity. Practical applications Vetiveria zizanioides is a medicinal plant with a variety of therapeutic applications in kidney‐related diseases. Apparently, it is used as a food ingredient due to its fresh and elegant scent and potential bioactivities. The aqueous root extract of V. zizanioides exerted relatively high antioxidant potential in vitro, substantiating the health effects of the plant pertaining to kidney diseases as a potential source of dietary antioxidant. The administration of the plant extract resulted in significant nephroprotection against doxorubicin‐induced experimental nephrotoxicity revealing the significance of V . zizanioides as a promising dietary supplement in the management of kidney disease.
