Embodiment 1
[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...
