Abstract

The invention discloses a preparation method of a traditional Chinese medicine composition for treating infection of the upper respiratory tract. In the invention, a diaphragm press filtration cycle extraction and separation integrative technology is adopted to replace a boiling method to be utilized for extraction of medicinal material active ingredients. Therefore, the preparation method simplifies a process flow, shortens a production period, reduces energy consumption, is beneficial for environmental protection and waste dreg utilization, and improves greatly a recovery rate of active ingredients.

Description

technical field [0001] The invention belongs to the field of pharmacy and relates to a preparation method of a traditional Chinese medicine composition. Background technique [0002] Chinese patent ZL200510008658.8 discloses a traditional Chinese medicine composition for treating upper respiratory tract infection, which is made of the following raw materials in the weight ratio: Artemisia annua 500-800 parts, honeysuckle 600-1000 parts, Schizonepeta 200-600 parts, 200-600 parts of Scutellaria baicalensis, 100-400 parts of Fangfeng and 100-400 parts of bellflower. Its preparation method is: adding 4-12 times of water to Artemisia annua, Schizonepeta, and Fangfeng, distilling for 4-8 hours, extracting volatile oil, collecting the distilled aqueous solution in another device, adding 4-14 times of water to medicinal dregs, honeysuckle, scutellaria, and Campanulaceae Decoct 1-3 times for 1-2 hours each time, combine the decoction, filter, combine and concentrate the filtrate and...
