Chrysophyllum albidum peel ethanol extract (CAPEE) was investigated for its antioxidant and hypolipidemic effects in rats. Dried peel was extracted in 70% ethanol and tested for phenolic content and in vitro antioxidant properties. Acute toxicity effect of CAPEE was tested at dose level of 2,000 mg/kg. The antioxidant and hypolipidemic effects in serum and hepatic tissues were evaluated in normal and triton-X-100-injected rats following 14 days of repeated treatment with CAPEE (50 and 200 mg/kg). Total phenolic content (TPC) and total flavonoid content (TFC) of CAPEE were 49.49 ± 2.48 mg GAE/g of sample and 14.71 ± 0.90 mg RE/g sample, respectively. The extract scavenged DPPH radical in a concentration-dependent manner with an IC50 of 63.1 ± 0.5 µg/mL. CAPEE (2,000 mg/kg) showed no sign of toxicity in mice. CAPEE (50 and 200 mg/kg) did not alter lipid profile in normal rats but ameliorated triton-X-100-induced increases in triglycerides and cholesterol and decrease in high-density lipoprotein (HDL). CAPEE showed hepatoprotective as well as antioxidant activity in serum and liver of normal and hyperlipidemic rats. The results revealed that Chrysophyllum albidum fruit peel ethanol extract possesses antioxidants and hypolipidemic properties.
