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 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 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 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 a freshly squeezed vacuum-dried powder decoction piece of Scutellaria barbata and a preparation process thereof. In this process, after the medicinal material of Scutellaria barbata is harvested, it is cleaned, rinsed, cut into sections, squeezed while it is fresh, and the medicinal juice is filtered. The dregs are mixed with water, filtered and pressed. The obtained medicinal juices are combined, concentrated under reduced pressure, dried in vacuum, crushed and packed in vacuum. The Scutellaria barbata powder decoction pieces prepared by this method retained the polar and non-polar active ingredients in the medicinal materials to the greatest extent. The decoction pieces are convenient for storage and transportation, convenient for dispensing, controllable in quality, and reliable in curative effect, which is of great significance to guarantee the clinical curative effect of traditional Chinese medicine. The popularization and implementation of this Law will 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...
