Embodiment 1

[0079] Embodiment 1: the preparation method of capsule for the treatment of pharyngitis and upper respiratory tract infection

[0080]Take 350g of Chuanshegan total flavonoids, put it into a hot air circulation dryer and dry it at a temperature of 80°C to 85°C so that the moisture content is lower than 5%, and use a universal pulverizer to prepare the Chuanshegan total flavonoids Pulverize, pass through a 60-mesh sieve, add talc powder of 2% total weight of Chuanshegan total flavonoids fine powder, mix in a multi-directional motion mixer for 30 minutes, make it mix evenly, and fill the uniform mixture into 1 capsule with a capsule filling machine. In No. 2 hard capsules, the Chuanshegan total flavonoids fine powder filled in each capsule is 0.35g, and 1000 capsules are made altogether.

Abstract

The invention provides a preparation method of a capsule preparation (Antaituo capsule) for treating pharyngitis and infection of the upper respiratory tract and a quality detection method of the capsule. The preparation method comprises the steps of: taking 350 g of iris tectorum maxim total flavonoids, drying to make the moisture content lower than 5%, smashing into fine powder which can pass through a 60-mesh screen, adding talcum powder accounting for1-3% by weight of the fine power,mixing evenly, and loading into a number one hard capsule. Besides a check on general projects according to the pharmacopoeia general rule, in the detection method, methods for identifying the main active ingredient tectoridin are formulated, comprising spectrophotometry and thin layer chromatography; the content of the iris tectorum maxim total flavonoids is determined through the spectrophotometry to ensure that the quantity of the active ingredient is more steady, and the quality of the preparation is effectively controlled to ensure the clinical effects, thereby the safe and effective medication for people is ensured.

Description

technical field [0001] The invention relates to a pure traditional Chinese medicine preparation, in particular to a preparation method of An Tai Tu capsule, a medicine for treating pharyngitis and upper respiratory tract infection, and a quality detection method thereof. Background technique [0002] An existing medicine for treating pharyngitis and upper respiratory tract infection is a traditional Chinese medicine decoction made by decocting the Chinese herbal medicine Chuanshegan. , laryngitis and acute upper respiratory tract infection caused by sore throat, hoarseness, cough yellow phlegm has a very good effect. However, it has the disadvantages of troublesome decoction, difficult storage, inconvenient carrying and taking, and inconvenient accurate dosage. Some people have extracted the active ingredients of Chuanshegan from the traditional Chinese medicinal material Chuanshegan, the total flavonoids of Chuanshegan, and took it directly. It also has the disadvantages o...
