Abstract

The invention belongs to the medicine preparation field and discloses a method for preparing Dandeng Tongnao pharmaceutical preparation and a quality control method. The preparation method is as follows: firstly, volatile oil extracted from hemlock parsley is standby or cladded and then residue and kudzu root are extracted water and precipitated alcohol, filtered and concentrated into concentrated solution A; secondly, Salvia miltiorrhiza and Erigeron breviscapus are extracted alcohol, filtered and concentrated into concentrated solution B; thirdly, the concentrated solution A and the concentrated solution B are mixed, concentrated into thick paste and then dried and crushed; volatile oil clathrate powder is added into the mixture, and extracted dry medicinal powder is obtained; fourthly, or the concentrated solution A and the concentrated solution B are mixed; the standby volatile oil is added into the mixture which is then uniformly mixed and filtered, and extracted liquid medicine is obtained; fifthly, the corresponding pharmaceutical preparation is prepared by addition of auxiliary materials which can be accepted pharmaceutically by the extracted dry medicinal powder or the extracted liquid medicine. The quality control method comprises the following steps of content test and content discrimination, wherein, the content test takes puerarin and tanshinone II A as the index, and the content discrimination takes hemlock parsley contrast medicine, puerarin and scutellarin as the contrast. The method is simple in preparation technique and short in production period and is suitable for industrial production; and the quality control method comprehensively guarantees the product quality.

Description

technical field [0001] The invention belongs to the field of pharmacy, and relates to a preparation method and a quality control method of a medicinal preparation of Dandeng Tongnao. Background technique [0002] "Stroke" is the main killer of cardiovascular disease, and more than two million people die of stroke every year.
