Result of study shows: alcohol precipitation concentration is 70% o'clock, and the impurity of removing is maximum, and simultaneously pharmacologically active is the highest, therefore, selects for use 70% concentration of alcohol as the concentration of removing impurity.
The research of concentration technology: the applicant has investigated concentrating under reduced pressure and normal pressure concentrates two kinds of methods, find through preferred, concentrating under reduced pressure and normal pressure concentrate two kinds of methods relatively, concentrating under reduced pressure is concentrated fast than normal pressure, save time, and pharmacologically active is concentrated higher than normal pressure, therefore, selects the method for concentration of concentrating under reduced pressure as the preparation of this extract.
Drying process: the applicant discovers that baking temperature has certain influence to the pharmacologically active of extract, and this extract is best at the pharmacologically active of 75 ℃ of drying under reduced pressure, therefore, selects the drying means of 75 ℃ of drying under reduced pressure as this extract.
Two, the research of Herba Polygoni cymosi alcohol extraction technology
The principal element that influence is extracted has: extraction time, solvent consumption, solvent concentration and extraction time etc., the applicant is through discovering: the extraction process that optimizes by the following method can be thought the best alcohol extraction technology of Herba Polygoni cymosi, and the extract curative effect of gained is best.
It is an amount of to get the Herba Polygoni cymosi medical material, is ground into fine powder, tests by table 5, the results are shown in Table 6, table 7:
