Problems solved by technology

The preparation process of granular decoction pieces, the extraction is not only time-consuming and energy-consuming, but also because a large amount of water is often used as a solvent, it is difficult to extract the non-polar active ingredients in the medicinal materials
In addition, since the dandelion medicinal material used for extraction is also dried and stored for a long time, the loss of active ingredients is also great

Embodiment 1

[0012] The freshly collected dandelion medicinal materials are cleaned, washed with water to remove the sediment, and pressed 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, add the ba...

Embodiment 2

[0014] The freshly collected dandelion medicinal materials are cleaned, washed with water to remove the sediment, and pressed 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 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 the bagged antioxid...

Abstract

The invention discloses freshly squeezed freeze drying Mongolian dandelion herb powdery decoction pieces and a preparation process thereof. The process is characterized by harvesting the medicinal material Mongolian dandelion herb, then cleaning, selecting and drip-washing Mongolian dandelion herb, squeezing Mongolian dandelion herb while Mongolian dandelion herb is fresh and taking the juice after filtration; adding water to the dregs, stirring the dregs and carrying out filtering and squeezing; mixing the obtained juice and then carrying out vacuum concentration, carrying out freeze drying, collecting the freeze-dried product and carrying out vacuum packaging after grinding. The Mongolian dandelion herb powdery decoction pieces prepared by the method furthest retain the polar and nonpolar active ingredients in the medicinal material, are easy to store and transport and convenient to regulate, are controllable in quality, have reliable curative effects and have great significance in guaranteeing the clinical effects of traditional Chinese medicines. Popularization and implementation of the method has remarkable social significance and economic benefits.

Description

technical field [0001] The invention belongs to the field of processing Chinese medicinal materials, and in particular relates to a processing technology of Chinese medicinal dandelion decoction pieces. Background technique [0002] Dandelion, a traditional Chinese medicine, is a dandelion Taraxacum mongolicum Hand.-Mazz., Alkaline Dandelion Taraxacumborealisinense Kitam. or the dried whole herb of several plants of the same genus. This product is bitter, sweet and cold. Return liver, stomach warp. It has the effects of clearing away heat and detoxification, reducing swelling and dispelling stagnation, diuresis and treating stranguria. Clinically, it is mainly used to treat boils and swollen toxins, mastitis, scrofula, red eyes, sore throat, lung abscess, intestinal fistula, damp-heat jaundice, hot dripping pain, etc. [0003] The commonly used processing methods of dandelion decoction pieces are: excavate when the flowers first bloom from spring to autumn, remove impu...
