Description

technical field

[0001] The invention relates to the use of iris total flavonoids extract, which belongs to the field of traditional Chinese medicine. Background technique

[0002] According to traditional Chinese medicine, acute pharyngolaryngitis belongs to the external attack of wind-heat evil poison, and throat obstruction (acute pharyngitis) and acute throat dullness (acute laryngitis) caused by evil heat blocking the lungs are common and frequently-occurring diseases that seriously affect health, often accompanied by Produced by a cold. The onset is acute, with sore throat, hoarseness, headache, fever, and cough with yellow sputum as the main symptoms, and further exacerbation may cause edema and congestion of the throat and nasal mucosa. Modern medicine has confirmed that acute pharyngitis is mostly caused by viruses, mainly including influenza virus, parainfluenza virus, adenovirus, Coxsackie virus, respiratory syncytial virus, rhinovirus, etc. Antibiotics are ineffe...

[0025] Embodiment 1 The preparation of the total flavonoids of the drug extract iris of the present invention

[0026] (1) The crude drug is crushed into a coarse powder and passed through a 20-mesh sieve, placed in an extraction tank, heated and refluxed with 70% ethanol to extract three times, each time for 1.5 hours, and the amount of each solvent is 4 times the amount of the medicinal material (v / w) , Combine the extracts, filter, and recover ethanol under reduced pressure at 60°C to obtain a syrupy substance (brown yellow extract) with a specific gravity of 1.2g / ml (measured at 50°C). Its yield is 49-51% (w / w) of the feed amount. Stir and dissolve the above-mentioned extract with boiling water (w / w) equivalent to 20 times the amount of the raw drug. The dosage is 3:1, w / w), the flow rate is controlled at 5-10 liters per minute per 100kg resin, the effluent is discarded, and the reaction of magnesium hydrochloride powder in the effluent turns slightly red (take 1ml of the...
