Abstract

The invention discloses a preparation and an application of an anti-inflammatory effective part of rhaponticum uniflorum. The preparation method comprises the following main steps: carrying out reflux extraction on rhaponticum uniflorum with ethyl alcohol, and recovering ethyl alcohol; separating an alcohol extract with D101 or AB-8 macroporous resin; and eluting with 50%-90% ethyl alcohol, and concentrating and drying an eluant, so as to obtain the anti-inflammatory effective part of the rhaponticum uniflorum. The anti-inflammatory effective part of the rhaponticum uniflorum disclosed by the invention has relatively good anti-inflammatory activity on acute and chronic inflammations, and is simple in process and suitable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular, the invention relates to a preparation method (extraction and separation) of the anti-inflammatory effective part of the Mongolian medicine Leu reed flower and the application of the effective part. Background technique [0002] Inflammation is a very common and important basic pathological process, which can occur in any part of the body and any tissue. Most human diseases are often related to inflammatory processes. Inflammation is also the most important protective response of the body, and the long-term survival of human beings is inseparable from the inflammatory response. But in some cases, the inflammatory reaction also has different degrees of harm to the body, and the severe inflammatory reaction can even endanger the life of the patient. Therefore, it will be of great significance to actively develop various drugs to prevent and control the adverse effects of inflam...
