Probing the anti-hyperlipidemic efficacy of the allspice (Pimenta officinalis Lindl.) in rats fed with high fat diet.

In this study, the anti-hyperlipidemic effect of aqueous extract of Pimenta officinalis (APO) was investigated in experimental rats fed with high fat diet (HFD). Hyperlipidemia in experimental rats was evidenced by a significant enhancement in the level of glycerol, triglycerides and phopholipids in serum, and also in liver and kidney tissues. HFD caused oxidative stress in these animals as shown by marked increment in the levels of thiobarbituric acid reactive substances (TBARS) and diene conjugates (CD), and a distinct diminution in reduced glutathione (GSH) content in liver and kidneys. Antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) showed reduced activity in hyperlipidemic rats. All these biochemical parameters showed reliable signs of retrieving towards near-normalcy in APO-administered HFD fed rats. This study unveiled the anti-hyperlipidemic as well as antioxidant activity of APO.
