Embodiment 1

[0012] Clean the freshly collected herbal medicinal materials, wash them with water to remove the sediment, cut them into 3cm sections, and squeeze them with a press to get the juice while they are 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 is 1.05, it is spray-dried, the air inlet temperature is 140°C, and the air outlet temperature is 100°C, collect the spray-dried matter, crush it at low temperature, pass through an 80-mesh sieve, and pack it into a bag with a moisture content not higher than 12%. , 1kg / bag, add antioxidant and desiccant in bags, vacuum seal an...

Embodiment 2

[0014] Clean the freshly collected herbal medicinal material, wash it with water to remove the sediment, cut it into 6cm sections, and squeeze it with a press to extract the juice while it is 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 is 1.10, spray dry, the temperature of the air inlet is 120°C, and the temperature of the air outlet is 90°C, collect the spray-dried matter, crush it at low temperature, pass through a 60-mesh sieve, and the moisture content is not higher than 12%, and pack it into a bag , 1kg / bag, add antioxidant and desiccant in bags, vacuum seal ...

Abstract

The invention discloses potentilla discolor freshly squeezed spray-dried powder decoction slices and a preparation method thereof. The process comprises the following steps: collecting a potentilla discolor medicinal material, selecting, rinsing and cutting into pieces; squeezing when the medicinal material is fresh, and filtering to obtain medicinal juice; stirring the medicinal residues with water, filtering and squeezing; mixing the medicinal juices; and concentrating at reduced pressure, drying by spray, collecting the spray-dried product, grinding and packaging in vacuum. According to the potentilla discolor freshly squeezed spray-dried powder decoction slices prepared by the method, polar and nonpolar effective ingredients in the medicinal materials can be furthest maintained. The decoction slices are beneficial to storage and transportation, are convenient to prepare, have controllable quality and reliable curative effect, and have an important meaning to clinical curative effect guarantee of traditional Chinese medicines. Popularization and implementation of the process have remarkable social meaning and economic benefit.

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 common processing methods of the Herbs decoction pieces 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, and...
