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 plantain medicinal materials used for extraction are also dried and stored for a long time, the loss of active ingredients is also great

Embodiment 1

[0012] The freshly collected plantain herbs are selected, washed with water to remove the sediment, and squeezed with a press to extract the juice while it is fresh. Add 3 times the amount of drinking water to the obtained dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract 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 1.15, transfer it to a vacuum drying oven, dry at 60°C for 8 hours, pass through a 60-mesh sieve after crushing, pack into bags, 1kg / bag, add antioxidants and desiccants in bags, and vacuum seal That's it.

Embodiment 2

[0014] The freshly collected plantain herbs are selected, washed with water to remove the sediment, and squeezed with a press to extract the juice while it is fresh. Add 5 times the amount of drinking water to the obtained dregs, stir for 30 minutes, and press with a plate-and-frame filter press to extract 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, transfer it to a vacuum drying oven, dry at 65°C for 6 hours, pass through a 60-mesh sieve after crushing, pack into bags, 1kg / bag, add antioxidants and desiccants in bags, and vacuum seal That's it.

Abstract

The invention discloses freshly-squeezed vacuum-dried herba plantaginis powder decoction pieces and a preparation technology thereof. The technology comprises the steps that herba plantaginis is harvested and then selected, leached and squeezed when herba plantaginis is fresh, and medicine juice is leached; medicine residues are stirred by adding water, filtered and squeezed; obtained medicine juice is mixed and then concentrated under reduced pressure, vacuum-dried, crushed and vaccum-packaged. The herba plantaginis powder decoction pieces prepared through the method retain polar and nonpolar effective ingredients in the medicinal material to the maximum limit, are beneficial for storage and transportation, convenient to make up, controllable in quality and reliable in treatment effect and have the important significance on traditional Chinese medicine clinical effect ensuring. Implementation and popularization of the method have the significant social meaning and economic benefit.

Description

technical field [0001] The invention belongs to the field of processing Chinese medicinal materials, and in particular relates to a processing technology of decoction pieces of Chinese medicinal plantain. Background technique [0002] Plantago Plantaginaceae Plantago asiatica L. or flat car front Plantago depressa Dried whole herb of Willd. This product has the effects of clearing heat and diuresis, eliminating phlegm, cooling blood and detoxifying. For hot stranguria astringent pain, edema oliguria, diarrhea due to heat-dampness, cough due to phlegm-heat, hematemesis and epistaxis, carbuncle sore and so on. [0003] The commonly used processing methods of plantain decoction pieces are: digging in summer, removing sediment, drying in the sun, and then packing 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 a...
