Objective:To research hesperidin on lipid metabolism disorder in hyperlipemia model rats. Methods:Fifty Wistar rats,half male and half female,were divided into 5 groups,were fed with high fat diet except normal group. The drng- treated groups were given the hesperidin(40,80. 160 mg·kg-1). 12 weeks later,after measured body weight,the killed rats were determined about the biochemical index of serum,blood stream change.
