Abstract

The invention discloses a preparation method of a crataegus scabrifolia extract. The method comprises the steps that 1, coarse powder of crataegus scabrifolia is taken and extracted with ethanol, a first extracting solution is taken and filtered, first filtrate is obtained, ethanol in the first filtrate is removed, and a first concentrated solution is obtained; 2, water is added to first filtered residues for extraction, a second extracting solution is obtained and filtered, and second filtrate is obtained; 3, the second filtrate is evaporated, ethanol is added to the evaporated second filtrate, standing is conducted, supernatant liquid and lower suspension liquid are obtained and filtered separately, third filtrate and fourth filtrate are obtained and mixed, ethanol is removed, a second concentrated solution is obtained, the second concentrated solution is mixed with the first concentrated solution, evaporation concentration is conducted, and the crataegus scabrifolia extract is obtained. The preparation method is simple, feasible and very beneficial to industrial production; it is proved through pharmacodynamics experiments on animals that the extract produced through the preparation method contains the effective ingredients for treating hyperlipidaemia, can be used for treating the hyperlipidaemia and can also be used for preparing health-related products for preventing and treating the hyperlipidaemia.
