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 Artemisia argyi leaves used for extraction are also dried and stored for a long time, the loss of active ingredients is also great

Embodiment 1

[0012] Freshly collected Artemisia argyi leaves are selected, rinsed with water, squeezed with a press to extract juice. Add 2 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 obtained medicinal dregs are squeezed into medicinal juice with a press. The above-mentioned 3 medicinal juices were combined, concentrated under reduced pressure, and the temperature was set at 65°C. When the relative density of the concentrated extract was 1.15, put it in -80°C and freeze it for 8 hours, then take it out and freeze-dry it at a pressure of 0.09Mpa, a temperature of -40°C, and a time of 24 hours. The freeze-dried product was taken out, ground and pulverized at low temperature. In addition, 5% by weight of NaCl was added to the condensed water of mugwort leaves collected during concentration under reduced pressure, and stirred to dissolve. The solution was placed in an oil-water separator ...

Embodiment 2

[0014] Freshly collected Artemisia argyi leaves are selected, rinsed with water, squeezed with a press to extract juice. Add 3 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 obtained medicinal dregs are squeezed into medicinal juice with a press. The above-mentioned 3 medicinal juices were combined, concentrated under reduced pressure, and the temperature was set at 60°C. When the relative density of the obtained concentrated extract was 1.10, it was frozen at -80°C for 12 hours, taken out, and freeze-dried at a pressure of 0.08Mpa, a temperature of -20°C, and a time of 48 hours. The freeze-dried product was taken out, ground and pulverized at low temperature. In addition, 3% by weight of NaCl was added to the condensed water of mugwort leaves collected during concentration under reduced pressure, and stirred to dissolve. The solution was placed in an oil-water separator and ...

Abstract

The invention discloses argy wormwood leaf powdery decoction pieces prepared through freshly pressing and freeze-drying and a preparation technology of the argy wormwood leaf powdery decoction pieces. According to the technology, argy wormwood leaf crude medicine is selected and leached after harvested and is pressed while the medicine is fresh, and medicine juice is obtained through filtration; water is added to medicine residues and stirred, a mixture is filtered and pressed; the obtained medicine juice is combined and subjected to reduced pressure concentration, and a product is subjected to freeze-drying. Meanwhile, volatile oil is separated from a concentrated condensate and mixed with a freeze-drying product, and a mixture is sieved and bagged. According to the argy wormwood leaf powdery decoction pieces prepared with the method, effective component in the crude medicine are reserved to the greatest extent; the decoction pieces are convenient to store, transport and adjust, have controllable quality and reliable treatment effect and have great significance in guarantee of a clinical treatment effect of traditional Chinese medicine; popularization and implementation of the technology have remarkable 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 mugwort leaves of traditional Chinese medicine. Background technique [0002] Artemisia argyi Artemisia argyi Dried leaves of Levl. EtVant. This product warms the meridians to stop bleeding, dispels cold and relieves pain, and is used externally for dispelling dampness and relieving itching. It is mainly used for the treatment of hematemesis, metrorrhagia, menorrhagia, fetal leakage, cold pain in the lower abdomen, irregular menstruation, cold uterine infertility, etc. [0003] The commonly used processing methods of Artemisia argyi leaves are: picking when the flowers are not in bloom in summer, removing impurities, drying, packing and transporting. This kind of traditional Chinese medicine decoction pieces is bulky, easy to be polluted and mildewed, has poor hygienic conditions, and ...
