BACKGROUND
Buxus sempervirens L. is used in Morocco as a plant with some medicinal properties including treatment of diabetes and cardiovascular diseases.
METHODS
The objective of the study was to assess the effect of the aqueous extract of Buxus sempervirens L. (Boxwood) leaves on the blood lipid parameters including total cholesterol, triglycerides, High-Density Lipoprotein Cholesterol (HDL-C), Low-Density Lipoprotein Cholesterol (LDL-C) and Very Low-Density Lipoprotein Cholesterol (VLDL-C) in normal and streptozotocininduced diabetic rats. In addition, antioxidant activity of aqueous Buxus sempervirens extract was evaluated by DPPH and FRAP assays.
RESULTS
The results indicated a significant decrease in serum total cholesterol and LDL-C levels, while, no change was observed on triglycerides and VLDL-C values in diabetic rats. Lipid profile of normal animals did not reveal any modification. In addition the aqueous extract of Buxus sempervirens exerted a significant antioxidant activity. Therefore, the results suggest that the aqueous extract of Buxus sempervirens exhibits lipid lowering activity which could be due partially to its antioxidant ability.
CONCLUSIONS
In conclusion, Buxus sempervirens leaf extract may be helpful in controlling the development of hyperlipidemia as well as atherosclerosis in diabetic animals.
