Abstract

In this study, lotus root(Nelumbo nucifera G.) which has been used in oriental medicine and folks remedy, was studied to apply to functional foods. We investigated the effects of the lotus root extracts(LTE) with hot water on the reduction of serum lipid and improvement of blood parameters in rats fed high fat diet for 5 weeks. Sprague-Dawley rats weigh $150g\pm15g$, were randomly assigned to 4 groups such as basal diet only(BDG), high fat diet without LTE(FDCG), high fat diet with $6\%$ LTE(FD6L), high fat diet with $12\%$ LTE(FD12L). The results of this study were as follows. Hematological data were not significantly different among 4 groups. Serum transferrin concentration and GOT activity were reasonable levels in FD6L and FD12L groups compared with FDCG group. Total cholesterol, LDL-cholesterol, triglyceride in serum and atherogenic index were remarkably reduced in LTE supplemented groups as compared with the control group. But HDL-cholesterol contents in FD6L and FD12L groups were significantly increased compared with that in control group. These results imply that lotus root extracts could be used as a potent food resources for decrease of serum lipid concentration.
