Lipid lowering and antioxidant potential of Asparagus racemosus in hyperlipidemic rats
Keywords:

Background: Atherosclerosis is associated with hyperlipidemia which is a major risk factor for coronary artery disease. Therefore, treatment of hyperlipidemia is one of the major approaches to decrease the atherogenic process. Many studies revealed that Asparagus racemosus (AR) possesses hypolipidemic and antioxidant potential, but results were not consistent. Therefore, the present study was undertaken to investigate lipid lowering and antioxidant potential of AR root powder in hyperlipidemic rats.
Methods: Hyperlipidemia was induced in normal rats by including 0.75 gm% cholesterol and 1.5 gm% bile salt in normal diet and these rats were used for the experiments. Dried root powder of Asparagus racemosus was administered as feed supplement at 5 gm% and 10 gm% dose levels to the hyperlipidemic rats. Plasma lipid profile, malondialdehyde, ascorbic acid, catalase and superoxide dismutase were estimated using standard methods. Statistical analysis was done by one way analysis of variance (ANOVA).
Results: Feed supplementation with 5 gm% and 10 gm% Asparagus racemosus resulted in a significant decrease in plasma cholesterol, LDL and significant increase in HDL. But there were no significant decrease in triglycerides and VLDL. The feed supplementation increased activities of catalase, superoxide dismutase and ascorbic acid content increased significantly in both the experimental groups (5 and 10 gm% supplemented groups). But there was no significant change in the concentration of malondialdehyde in these groups.
Conclusions: The present study demonstrated that addition of Asparagus racemosus root powder at 5 gm% and 10 gm% level as feed supplement reduces the plasma lipid levels and also acts as an antioxidant.
