The invention relates to blood lipid-lowering active fractions of forsythia suspensa and a preparation method and use of the same. The active fractions are ethyl acetate fractions obtained by concentrating an extract which is extracted from forsythia suspensa leaves by acetone and water. The compound of phillygenin prepared by the invention and the active fractions, namely the ethyl acetate fractions, at which the phillygenin is positioned have good antioxidant activity in vitro. In-vivo experiments show that the ethyl acetate fractions and the phillygenin can lower total cholesterols and low-density lipoprotein cholesterin in the blood serum of a mouse with hyperlipidemia and can lower blood lipid level by an oxidative approach (raising superoxide dismutase SOD and lowering malonydialdehyde MDA). In addition, the ethyl acetate fractions have a better effect of reducing the total cholesterols in the blood serum of the mouse than the phillygenin and cassia seed blood lipid-lowering tablets. The ethyl acetate fractions of the forsythia suspensa leaves can be further developed to play a role in the multi- target co-prevention and treatment of hyperlipidemia and other diseases and have a good application prospect.
