Embodiment Construction

[0005] After the Scutellaria baicalensis is harvested, it is cleaned to remove impurities such as sediment and non-medicinal parts, washed with tap water while fresh within 6 hours, and cut into 3mm thick slices. Add 5 times the weight of the tablet to 100°C purified water, stir for 30 minutes, filter, squeeze the dregs to extract the juice. Then add 8 times the weight of pure water to the medicinal residues, boil for 20 minutes to extract, filter while hot, squeeze the medicinal residues again, and collect the medicinal juice. Combine the above medicinal juices, concentrate under reduced pressure, set the temperature at 70°C, and concentrate to a clear paste with a relative density of 1.20. The obtained clear paste is vacuum-dried at 80°C until the water content is 8%, crushed, passed through a 60-mesh sieve, and vacuum-packed to obtain the finished product. The content of baicalin in the finished decoction pieces is 11.0%.

Abstract

The invention discloses a fresh radix scutellariae extract vacuum-dried powder decoction piece. A preparation method of the decoction piece comprises harvesting rhizoma rehmanniae, washing the fresh rhizoma rehmanniae, carrying out slicing, juicing and extraction, concentrating the extract to obtain clear paste, drying the clear paste in vacuum until water content of less than 10%, and carrying out crushing, sieving and vacuum packing. The powder decoction piece has water content of less than 10%. The quality of the decoction piece is stable. The decoction piece can be boiled in a decoction ordirectly used into pills, powder, tablets or capsules so that carrying and clinical use are convenient.
