Abstract

The present invention discloses an effective part of silverweed cinquefoil root for nourishing blood and a preparation method thereof. The present invention can be used in the art of drugs for nourishing blood and health care products. The silverweed cinquefoil root drugs for nourishing blood or health care products provided by the present invention takes dried fruits of silverweed cinquefoil root as the raw material; petroleum ether is used to extract the ethanol extract of silverweed cinquefoil root; the effective part for nourishing blood is obtained after the extract is decompressed and condensed through vacuum. The animal in vivo experiments show that the effective part of silverweed cinquefoil root can significantly increase the number of red blood cells and the content of hemoglobin in mouse blood. The present invention creates conditions for the application of silverweed cinquefoil root in drugs for nourishing blood or health care products.

Description

Technical field [0001] The invention belongs to the field of preparation of health products and natural medicines, and specifically relates to effective parts with blood-tonifying function extracted from Potentilla anserina and a preparation method thereof.
