Abstract

The invention discloses a preparation method of fritillary and loquat buccal tablets for treating cough, comprising the following steps of: (1) weighing raw materials; (2) decocting loquat leaf with water, filtering, concentrating to obtain clear paste, adding ethanol, fully mixing, standing, taking supernatant for later use; (3) pulverizing fritillary bulb, performing hot reflux extraction with ethanol on the fritillary bulb powder, balloonflower and typhonium flagelliforme, filtering, combining the filtrate with the supernatant obtained in the step (2), recycling the ethanol, concentrating to obtain clear paste, cooling to room temperature, adding butanone for extraction, recycling the butanone and concentrating to obtain thick paste; drying, pulverizing and screening the thick paste to obtain extract powder; and (4) adding 1-5 parts by weight of lubricant and 0-40 parts by weight of diluter to 1 part by weight of thick paste, and mixing uniformly to prepare buccal tablets. The fritillary and loquat buccal tablets for treating cough prepared from the raw materials extracted by the extraction method disclosed by the invention have small drug dose, high drug content and good curative effect, and are convenient to take and carry, conductive to quantitative administration and convenient to store and transport.

Description

technical field [0001] The invention relates to a preparation method of a traditional Chinese medicine preparation, in particular to a preparation method of Chuanbei loquat buccal tablet for treating cough.
