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 obtained concentrated extract was 1.15, it was transferred to a vacuum drying oven and dried at 60°C for 6 hours to obtain a vacuum-dried product. 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 and allowed to stand at 10°C for 24 hours to separate and collect the volatile oil in the upper layer. To this volatil...

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 concentrated extract was 1.10, it was transferred to a vacuum drying oven and dried at 60° C. for 8 hours to obtain a vacuum-dried product. 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 allowed to stand at 10°C for 24 hours, and the volatile oil in the upper layer was separated and collected. To this volat...

Abstract

The invention discloses folium artemisiae argyi fresh juice vacuum-dried decoction powder and a preparation process thereof. The process comprises the following steps: cleaning, selecting and leaching harvested folium artemisiae argyi medicinal materials, squeezing the medicinal materials when the medicinal materials are still fresh, filtering and reserving medicine juice; stirring medicine dregs in water once again, filtering and squeezing; combining obtained medicine juice, decompressing and concentrating, and vacuum-drying; and separating volatile oil from concentrated condensate, mixing the volatile oil with the vacuum-dried material, sieving and bagging. The folium artemisiae argyi decoction powder prepared by the method can reserve active ingredients in the medicinal materials to the greatest extent. The decoction powder is convenient for storage and transportation, convenient for blending, controllable in quality and reliable in treatment effect, and the decoction powder has an important significance for guaranteeing the clinical treatment effect of traditional Chinese medicine. The method, with popularization and implementation, can bring about apparent social significance and economical 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 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 ...
