Abstract

The crude extract of Rosmarinus officinalis L. (Rosemary) was tested on its effect on the cholesterol activity of albino rats. Hypercholesterolemia was induced to the albino rats by high-fat diet using buttered pellets. Normal baseline blood was collected prior to the administration of 50%, 75% and 100% extract of rosemary leaves. The study showed that the various concentration of extracted rosemary has a significant effect in lowering the blood cholesterol level of the albino rats. Best concentrations were also determined before treatment. The concentrations 75% and 100% were given to treatments as once daily and twice daily. Weekly monitoring of blood cholesterol was done for ten weeks. Using paired t-test and 0ne-way ANOVA, it was found out that there is a difference in the effect in lowering hypercholesterolemia (p<0.05). Inducing the albino rats with the two concentrations namely: T4=75% and T5=100% given dosing frequency of once daily and twice a day has no significant difference in lowering the blood cholesterol level. Results suggest that the extract have a potential property in controlling the lipid diet of an individual.
