Embodiment 1

[0012] Clean the freshly collected herbal medicine, wash it with water to remove the sediment, cut it into 3cm sections, and squeeze it with a press to extract the juice while it is fresh. Add 3 times the amount of tap water to the obtained dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract the juice. The remaining medicinal dregs are squeezed with a press to extract the juice. The above-mentioned 3 concoctions were combined and filtered with a 100-mesh sieve. The filtrate was concentrated under reduced pressure and the temperature was set at 65 °C. When the relative density of the concentrated extract was 1.15, the extract was frozen in a -80°C refrigerator for 6 hours. Take out the east knot, freeze-dry, the pressure is 0.09Mpa, the temperature is -20 ℃, dry for 24 hours. Take out the freeze-dried product, crush it at low temperature, pass through an 80-mesh sieve, the moisture content is not higher than 12%, pack it into a bag, 1kg / bag, ...

Embodiment 2

[0014] Clean the freshly collected herbaceous herbs, wash them with water to remove the sediment, cut them into 5cm sections, and squeeze them with a press to extract the juice while they are fresh. Add 5 times the amount of tap water to the obtained dregs, stir for 30 minutes, and press with a plate-and-frame filter press to extract the juice. The remaining medicinal dregs are squeezed with a press to extract the juice. The above-mentioned 3 concoctions were combined and filtered with an 80-mesh sieve. The filtrate was concentrated under reduced pressure and the temperature was set at 70 °C. When the relative density of the concentrated extract was 1.10, the extract was frozen in a -80°C refrigerator for 8 hours. Take out the east knot, freeze-dry, the pressure is 0.08Mpa, the temperature is -40 ℃, dry for 48 hours. Take out the freeze-dried product, crush it at low temperature, pass through a 60-mesh sieve, the moisture content is not higher than 12%, bag it, 1kg / bag, add...

Abstract

The invention discloses potentilla discolor freshly squeezed freeze-dried powder decoction pieces and a preparation process thereof. The process comprises the steps: after harvesting a potentilla discolor medicinal material, selecting cleanly, drip-washing, cutting into sections, squeezing while being fresh, and filtering to obtain a juice; and adding water to drug dregs and stirring, filtering and squeezing; and merging the obtained medicinal juices, carrying out reduced pressure concentration, freeze-drying, collecting a freeze-dried product, crushing the freeze-dried product, and then carrying out vacuum package. The potentilla discolor powder decoction pieces prepared by the method allows polar and non-polar active ingredients in the medicinal material to be retained at the same time to a greatest extent. The decoction pieces are beneficial for storage and transportation, convenient to adjust, controllable in quality, and reliable in curative effect, and has important significance on guaranteeing clinical curative effects of traditional Chinese medicines. The popularization and implementation of the preparation process can have significant social significance and economic benefits.

Description

technical field [0001] The invention belongs to the field of processing traditional Chinese medicinal materials, and in particular relates to a processing technology of traditional Chinese medicinal herba baicao decoction pieces. Background technique [0002] The traditional Chinese medicine P. Potentilla discolor Dry whole grass or aerial parts of Bge. This product clears heat and detoxifies, cools blood and stops bleeding, and can be used to treat dysentery, diarrhea, leucorrhea, malaria, blood in the stool, red dysentery, abdominal pain, hemorrhoids and other diseases. [0003] The commonly used processing methods of the Herbs decoction are as follows: Harvest in summer and autumn, remove impurities, dry in the sun, and pack for storage and transportation. Such herbal decoction pieces are bulky, have poor hygienic indicators, are prone to pollution and mildew, and are difficult to guarantee quality, which is not conducive to formula adjustment and clinical efficacy, an...
