Abstract

The invention relates to a pharmaceutical composition for treating neurasthenia and a preparation method thereof. The pharmaceutical composition comprises the following active ingredients: 0.03-0.5mg / ml eleutheroside E, 0.05-0.5mg / ml syringin, 0.005-0.05mg / ml isofraxidin and 0.03-0.5mg / ml schizandrin; preferably, 0.05-0.2mg / ml eleutheroside E, 0.1-0.3mg / ml syringin, 0.01-0.03mg / ml isofraxidin and 0.05-0.2mg / ml schizandrin. The pharmaceutical composition provided by the invention has the advantages that the preparation process is simple and feasible, the properties of the traditional Chinese medicine components are fully considered in the preparation process, excessive impurities are removed by macroporous adsorption resin to improve the concentration of active ingredients in the preparation and play the effects of the traditional Chinese medicine components; meanwhile, the used resin can be repeatedly used, so that resource consumption can be reduced. The traditional Chinese medicine composition prepared in the invention has a remarkable curative effect.
