Problems solved by technology

In addition to traditional decoction pieces, there are two forms of ultrafine powder decoction pieces and concentrated granule decoction pieces in the market, but both of them use traditional decoction pieces as raw materials, and their quality depends on the quality of traditional decoction pieces, and ultrafine decoction pieces cannot solve the problem. The problem of medicinal material contamination; concentrated granules can only extract water-soluble components

Embodiment Construction

[0005] After the angelica medicinal materials are harvested, they are cleanly selected to remove impurities such as sediment and non-medicinal parts, washed with tap water within 6 hours while fresh, and cut into 3mm thick slices. Add this tablet to 5 times the weight of purified water at 70°C, stir for 30 minutes, filter, and squeeze the medicine residue to extract the juice. Then add 8 times the weight of purified water to the above-mentioned medicinal residue, boil for 20 minutes to extract, filter while hot, extract the medicinal residue again, and collect the medicinal juice. The above-mentioned medicinal juice was combined, concentrated under reduced pressure, and the temperature was set to 70°C, and concentrated to a clear ointment with a relative density of 1.20. After freezing the obtained clear paste at -80°C for 12 hours, it was vacuum freeze-dried at -40°C. The dried product is vacuum dried at 60°C to a moisture content of 8%, crushed, passed through a 60-mesh siev...

Abstract

The invention discloses a fresh extraction and freeze drying powdery decoction piece of radix angelicae sinensis. The fresh extraction and freeze drying powdery decoction piece is mainly characterizedby being prepared by the following steps: after harvest, washing, slicing, squeezing and extracting fresh radix angelicae sinensis; after concentration of an extracting solution into clear paste, performing freeze drying; performing smashing, sieving and vacuum packaging. The powdery decoction piece is less than 10 percent in water content. The decoction piece is stable in quality, can be decocted in a decoction, can be directly added into pills, powder, tablets and capsules, is convenient to carry, and is convenient for clinical application.

Description

Technical field [0001] The invention belongs to the technical field of traditional Chinese medicine decoction pieces, in particular to the processing field of angelica decoction pieces. Background technique [0002] Angelica sinensis Angelica sinensis (Oliv.) The dry root of Diels. The traditional processing method of angelica is: excavate in late autumn to remove the fibrous roots and silt. After the moisture evaporates, they are bundled into small bundles, put on the shed, slowly dried with firework, then bundled, packaged, stored and transported. After arriving at the decoction piece factory, they are washed, softened, sliced, dried, and packaged. This kind of decoction pieces are large in size, poor in hygiene standards, prone to moisture, mildew, and insects, which is not conducive to storage and high storage and transportation costs. In addition, such decoction pieces have poor quality stability, difficult to guarantee clinical efficacy, inconvenient administration for p...
