Abstract
The invention discloses a drug preparation method of Ditong rhinitis water, which takes the following Chinese medicinal materials as raw materials: Mongolian dandelion herb, radix scutellariae, Chinese ephedra, cocklebur fruit, magnolia flower, dahurian angelica, asarum herb and the like. The preparation method comprises the following steps: distilling the Chinese ephedra, the cocklebur fruit, the magnolia flower, the dahurian angelica, the asarum herb and rhizoma acori tatarinowii with water vapor, and collecting distillate for use; decocting dregs, the Mongolian dandelion herb and the radix scutellariae with water; filtering, concentrating coarse filtrate or not, carrying out microfiltration or ultrafiltration on the concentrated filtrate, and then concentrating; and adding the distillate such as the Chinese ephedra and the like, Tween 80, glycerol and ethylparaben in proper amount, adjusting pH to 6-7, adding water in full quantity, filtering and sub-packaging to obtain the Ditong rhinitis water. Compared with a water-extraction and alcohol-precipitation method, the Ditong rhinitis water obtained by the preparation method has improved quality, better clarity, better stability and higher retention ratio of total solids and effective ingredients.
Description
