Anti-common cold capsule preparation method

Abstract

The invention relates to an anti-common cold capsule preparation method, which comprises: taking honeysuckle, red peony root and dryopteris crassirhizoma, feeding the materials according to a certain ratio, adding water, decocting twice, filtering, mixing the filtrates, concentrating to obtain a clear paste with a relative density of 1.18-1.22, adding ethanol to achieve an ethanol alcohol content of 50-70%, uniformly stirring, standing to obtain a supernatant, filtering, recovering ethanol from the filtrate, concentrating to obtain an extract with a relative density of 1.18-1.22, standing the extract through a macroporous absorption resin, collecting the eluent, concentrating to obtain a thick paste with a relative density of 1.22-1.24, adding starch to the thick paste, uniformly mixing to obtain a mixture, placing the mixture into a vacuum dry box to dry to obtain a honeycomb dry paste with loose texture, crushing the dry paste, screening to obtain coarse powder, adding magnesium stearate to the coarse powder, uniformly mixing, and filling into a hollow capsule to obtain the anti-common cold capsule. According to the present invention, stability of the product can not be affected, energy source consumption can be reduced, the dried dry paste has the loose texture so as to be easily collected, crushed and screened, and no moisture absorption phenomenon is generated when filling the coarse powder into the hollow capsule.

Description

technical field [0001] The invention relates to the technical field of preparation of Chinese patent medicines, in particular to a preparation method of Kanggan capsules. Background technique [0002] Kanggan Capsule has the effect of clearing heat and detoxifying. It is used for colds caused by exogenous wind-heat. Symptoms include fever, headache, nasal congestion, sneezing, general fatigue and soreness. The preparation method is that honeysuckle, red peony root, and Mianma Guanzhong are fed according to the prescription ratio, decocted twice for 1.5 hours each time, filtered, and the filtrates are combined and concentrated to a clear paste with a relative density of 1.18-1.22 (at room temperature). Add ethanol to make the alcohol content of ethanol reach 50-70%, stir well, let it stand for 22-24 hours, filter the supernatant, recover the ethanol from the filtrate and concentrate it to an extract with a relative density of 1.18-1.22 (at room temperature). After passing t...

Problems solved by technology

[0003] However, there are mainly the following problems in the above-mentioned prior art: it takes about 40 hours to dry in a hot air circulation drying oven, the drying period is long, and the production cost is high; the drying temperature in a hot air circulation drying oven is 90° C. It can affect the stability of the product; the dry paste after drying in a hot air circulation drying oven is glue-like, which is difficult to close and crush, and consumes a lot of production man-hours; the powder after crushing has moisture absorption, which is not conducive to filling
