Problems solved by technology

Due to the time-consuming and energy-consuming extraction during the preparation of granule decoction pieces, and because 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 medicinal material of bamboo leaves used for extraction is also dried and stored for a long time, the loss of active ingredients is also very large

Embodiment 1

[0012] Wash the freshly collected herbaceous bamboo leaves, cut them into 1cm-wide slices, add 0.5 times the weight of the medicinal materials in water, stir for 15 minutes, and squeeze the juice while it is fresh. Add 2 times the amount of tap water to the obtained medicinal dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract the juice. The obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the above-mentioned 3 times of medicinal juice of bamboo leaves, filter through a 60-mesh sieve, concentrate the filtrate under reduced pressure, and set the temperature at 60°C. When the relative density of the concentrated extract was 1.10, it was transferred to a -20°C refrigerator and frozen for 12 hours. Freeze drying was carried out after taking out the frozen material, the temperature was set at -18°C, the pressure was 0.09Mpa, and the time was 24 hours. Collect the freeze-dried product, pulverize i...

Embodiment 2

[0014] Wash the freshly collected herb leaves of Bamboo, cut into 2cm wide slices, add 1 times the weight of the medicinal materials in water, stir for 30 minutes, and squeeze 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 obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the above-mentioned 3 times of medicinal juice of bamboo leaves, filter through a 100-mesh sieve, concentrate the filtrate under reduced pressure, and set the temperature to 70°C. When the relative density of the obtained concentrated extract was 1.05, it was transferred to a -20°C refrigerator and frozen for 8 hours. Freeze-dry after taking out the frozen material, the temperature is set at -40°C, the pressure is 0.09Mpa, and the time is 48 hours. Collect the freeze-dried product, pulverize it, pass through a 100-mesh sieve,...

Abstract

The invention discloses a preparation technology of freshly squeezed and freeze-dried Lophatherum gracile powder decoction pieces. The technology comprises the following steps: harvesting a Lophatherum gracile medicinal material, choosing the clean material, leaching the material, freshly squeezing the material, filtering the obtained juice, and taking obtained decoction; adding water to obtained medicinal residues, stirring the water and the medicinal residues, and performing filtration and squeezing; and mixing above obtained decoctions, carrying out reduced pressure concentration, and carrying out freeze drying to obtain the Lophatherum gracile powder decoction pieces. The Lophatherum gracile powder decoction pieces prepared through the technology maximally reserve the polar and non-polar effective components in the medicinal material, have the advantages of convenience in storage and transportation, convenience in dispensing, controllable quality and reliable curative effects, and is of great significance to guaranteeing the clinic curative effects of traditional Chinese medicine and pharmacy. The technology can be promoted and enforced to obtain remarkable social meaning 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 decoction pieces of traditional Chinese medicine Danzhu leaves. Background technique [0002] The traditional Chinese medicine Pachyphyllum is a perennial herb of the Poaceae Pachyphyllum genus. It has the effects of cooling, antipyretic, diuretic and inducing labor. Clinical indications: fever in the chest, coughing up qi, hematemesis, heat-toxin wind, relieving thirst, suppressing alchemy and stone poison, eliminating phlegm, treating mania and depression, apoplexy due to apoplexy, headache and wind, relieving palpitations, etc. [0003] The commonly used processing method of decoction pieces of light bamboo leaves is as follows: after harvesting, impurities are removed, dried in the sun, directly packaged for storage and transported. The hygienic indicators of these dry bamboo leaves cannot meet the stand...
