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 Liu Jinu 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] Wash the freshly collected Liu Jinu herbs, cut them into 1cm-long sections, add water 0.5 times the weight of the herbs, 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 three Liu Jinu medicinal juices, 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 it, pass through a 60-mesh sieve, pack it into b...

Embodiment 2

[0014] Wash the freshly collected medicinal herbs of Liu Jinu, cut them into 2cm-long sections, add 1 times the weight of the medicinal herbs 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. The above 3 Liu Jinu medicinal juices were combined, filtered through a 100-mesh sieve, the filtrate was concentrated under reduced pressure, and the temperature was set at 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 Artemisia anomala freshly-squeezed freeze-dried powder decoction pieces. According to the technology, after Artemisia anomala medicinal materials are collected, sorting, rinsing and fresh squeezing are conducted, and a decoction is obtained from filtering; water is added into dregs for stirring, and filtering and squeezing are conducted; after obtained decoctions are mixed, the mixture is subjected to vacuum concentration and freeze-dried. According to the technology, Artemisia anomala powder decoction pieces are obtained, and polar and non-polar effective components in the medicinal materials are kept to the utmost extent at the same time; the decoction pieces have the advantages of being easy to store and transport, convenient to make as a prescription, controllable in quality, reliable in curative effect and of great importance in guaranteeing clinical effectiveness of traditional Chinese medicine; popularization and implementing of the technology will have significant social meaning and economic benefit.

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 Liu Jinu. Background technique [0002] Liu Jinu Artemisia anomala Whole Herb of S. Moore. It has the effects of dispelling blood and dredging menstruation, suppressing sores and detumescence. Clinically, it is mainly used to treat symptoms such as amenorrhea, chest pain, postpartum blood stasis, bruises, gold sore bleeding, and carbuncle. [0003] The commonly used processing methods of Liu Jinu decoction pieces are: remove impurities after harvesting, dry in the sun, and pack directly for storage and transportation. The hygienic indicators of these dried Liu Jinu cannot meet the standards, and the medicinal materials are prone to mildew, which leads to the decline of the quality of the medicinal materials and the reduction of the clinical efficacy. ...
