Abstract: Background: This study investigated the phytochemical composition and toxicity profile of Persea americana seed oil (PASO) in albino Wistar rats. Methods: Chromatography-mass spectrometry (GC-MS) was used to analyse the chemical constituents of PASO. For the acute toxicity test, PASO was administered orally in a single dose of up to 3000 mg/kg body weight (bw). For the subacute toxicity test, the rats were divided into four (4) groups. Group I (normal control), while groups II, III and IV received 200, 300 and 400 mg/kg PASO daily, respectively, for 14 days. Results: In the acute toxicity test, the lethal dose (LD 50 ) of PASO was estimated to be 1477.83 mg/kg. In the subacute toxicity test, PASO significantly increased (p < 0.05) aspartate aminotransferase, creatine phosphokinase, alanine aminotransferase, creatinine, alkaline phosphatase, urea, malondialdehyde, high density lipoprotein, interleukin 1-beta (IL-1β), tumour necrosis factor (TNF-α) and cardiac troponin and significantly decreased glutathione, red blood cells (RBC), packed cell volume (PCV), superoxide dismutase and catalase compared to the control group. Conclusion: Our study showed that the LD 50 of PASO is 1477.83 mg/kg body weight, which classifies it as a toxic substance. In subacute toxicity, our results revealed that treatment with PASO resulted in an increase in liver enzymes, urea and creatinine, and inflammatory markers, and a decrease in antioxidant enzymes, suggesting that PASO impairs liver and kidney functions and may cause cardiac or muscle damage in albino Wistar rats. • PASO decreased antioxidant enzymes, RBC, PCV and increased MDA • PASO increased interleukin 1-beta (IL-1β) and tumour necrosis factor (TNF-α) • PASO reduced lipid profile parameters and may have anti-atherogenic activities • PASO increased ALP, AST, ALP, creatinine, urea and induces hepatic and renal toxicity
