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 Scutellaria barbata 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 Scutellaria barbata medicinal material is selected, washed with water to remove the sediment, cut into 3cm sections, and squeezed 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 i...

Embodiment 2

[0014] The freshly collected Scutellaria barbata medicinal material is selected, washed with water to remove the sediment, cut into 6cm sections, and squeezed 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,...

Abstract

The invention discloses Scutellaria barbata fresh squeezed freeze-drying powder slices and a preparation process thereof. The process comprises: harvesting Scutellaria barbata medicinal material, cleaning, washing, cutting, squeezing while fresh, and filtering a medicinal soup; mixing the dregs with water, filtering and squeezing; combining the obtained medicinal soup, conducting decompression concentration, freeze-drying, collecting freeze-drying products, crushing and vacuumizing. The prepared Scutellaria barbata powder slices maximally retain the polar and non-polar constituents in the medicinal materials. The slices are convenient for storage and transportation, easy to regulate, controllable in quality and reliable in curative effect, and very important to ensure the clinical curative effect of traditional Chinese medicine. The popularization and implementation of the method have significant social 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 for decoction pieces of the traditional Chinese medicine Scutellaria barbata. Background technique [0002] Banzhilian Scutellaria barbata D. Don's dried whole herb. This product has heat-clearing and toxic substances removing, promoting blood circulation and removing blood stasis, reducing swelling and alleviating pain, and anti-cancer merit. Clinically, it is often used to treat appendicitis, hepatitis, cervical cancer, mastitis, etc.; external application can treat boil pain, bruises, swelling pain, etc. [0003] The commonly used processing methods of Scutellaria barbata are: harvesting in summer and autumn, removing impurities, washing, drying in the sun, and then packaging for storage and transportation. Such herbal decoction pieces are bulky, have poor hygienic indicators, are prone to pollution and mi...
