Abstract:

Objective: To investigate the effect of methanolic leaf extract of Talinum triangulare on hematological parameters, enzymatic and non-enzymatic antioxidant status,and serum lipid in Wistar rats fed standard laboratory, or 2% cholesterol-enrich diet. Material and Methods: Wistar rats (180-210g) divided into six groups of six animals (males) each were fed 2% cholesterol-enriched diet and orally treated with 0.9% saline or extract of Talinum triangulare (250, 500, and 1000 mg/kg per body weight) daily for eight weeks. Lipid profile, lipid peroxidation (MDA), hematological parameters, and their functional indices and serum antioxidant enzymes (catalase, glutathione -S-transferase, and superoxide dismutase) activities and glutathione status were assessed in normal and diet-induced hypercholesterolemic extract treated rats and compared with the rats treated with 100 mg/kg per bwt standard drug gemfibrozil. Results: A significant (P < 0.05) increase in lipid profile (total glyceride, total cholestrol, low-density lipoprotein, and very low-density lipoprotein), MDA and reduction (P < 0.05) in enzymatic and nonenzymatic antioxidant status coupled with alterations in hematological parameters was observed in the serum of hypercholesterolemic rats when compared with animals on a normal diet. Coadministration of methanolic leaf extracts of Talinum triangulare or gemfibrozil significantly (P < 0.05) restored the elevated serum lipid profile, MDA, and the deranged hematological parameters to near normal. The extract also protected against hypercholesterolemic-induced diminished enzymatic and nonenzymatic antioxidant status. The activities of the plant extract are dose (250, 500, and 1000 mg/kg) dependent and it compared favorably with the standard drug gemfibrozil. Conclusion: The present study suggested that the extract of Talinum triangulare might protect against hypercholesterolemic-induced altered lipid profiles, oxidative stress, and also improve the status of antioxidant defense system and hematopoiesis.
