Effects of cassia seed,red yeast rice,ginkgo biloba leaf and salvia miltiorrhiza compounds on blood lipid level of rats / 预防医学

ABSTRACT

Objective @#To learn the effects of cassia seed extract,ginkgo biloba leaf extract,salvia miltiorrhiza extract and red yeast rice compounds on blood lipid level of rats with hyperlipidemia. @*Methods @#The model of hyperlipidemia in SD rats was established. The rats in the low,moderate and high dose groups were given 0.267 g/kg body weight,0.533 g/kg body weight and 1.600 g/kg body weight of cassia seed,red yeast rice,ginkgo biloba leaf and salvia miltiorrhiza compounds by gavage for 30 days. A blank control group and a model control group were also set. The levels of serum total cholesterol（TC）,triglyceride（TG）,high-density lipoprotein cholesterol（HDL-C）and low-density lipoprotein cholesterol（LDL-C）in the five groups were measured before and after the intragastric administration. @*Results @#One week after the model was founded,the levels of serum TC,TG and LDL-C in the model control group were higher than those in the blank control group（P<0.05）. Before the intragastric administration,there were no significant differences in the levels of serum TC,TG,HDL-C and LDL-C between the model control group and each dosage group（P>0.05）. After the intragastric administration,there were no significant differences in the levels of serum HDL-C and LDL-C between the model control group and each dosage group（P>0.05）. The levels of serum TC and TG in the high dose group were significantly lower than those in the model control group（P<0.05）;There was no significant differences in the levels of serum TC and TG between the moderate dose,low dose group and the model control group（P>0.05）. @*Conclusion@# The compounds of cassia seed extract,red yeast rice,ginkgo biloba extract and salvia miltiorrhiza extract with a dosage of 1.600 g/kg body weight can reduce serum TC and TG levels in rats with hyperlipidemia.
