Abstract

The invention discloses a preparation method of heat clearing and detoxifying soluble powder. The soluble powder is prepared on the basis of a veterinary use preparation ''Summer-heat clearing mixture'' through dosage form change and technology optimization. The drug stability and practicability are improved by changing a liquid preparation into a solid preparation, and the storage and transport are easy. A preparation technology of traditional Chinese medicine soluble powder is optimized. Chitosan and sodium alginate are combined to remove insoluble components of precipitation, insoluble suspension particles, tannin and colloid in an extracted liquid. The water soluble property of the soluble powder is improved, the administration of drinking water is facilitated, and the practicality of the drug is enhanced. The heat clearing and detoxifying soluble powder prepared by the method has the high baicalin retention rate, good water soluble property and stable quality, and is easy to store and easy to transport. The method of the invention realizes alcohol-free production. The technology is simple. The production period is short. The equipment requirement is low, and the cost is low. The preparation method of the heat clearing and detoxifying soluble powder facilitates large scale popularization, exploitation and application.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese veterinary medicine, and in particular relates to a preparation method of heat-clearing and detoxifying soluble powder. Background technique [0002] "Chinese Veterinary Pharmacopoeia" 2010 edition of Qingjie mixture: 670g gypsum, 140g honeysuckle, 100g scrophulariaceae, 80g scutellaria baicalensis, 80g rehmannia root, 70 parts forsythia, 70g gardenia, 60g gentian, 60g sweet dithin, Banlangen 60g, Anemarrhena 60g, Ophiopogon japonicus 60g, the extraction method is: the above 12 flavors, except honeysuckle and scutellaria baicalensis, soak the other 10 flavors in water for 1 hour, then decoct 2 times, the first time for 1 hour (decoction for half an hour) Then add honeysuckle and scutellaria baicalensis), decoct for 40 minutes for the second time, filter, combine the filtrate, concentrate the filtrate to a relative density of about 1.17 (90°C), add ethanol to make the alcohol content re...
