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 annua used for extraction is also dried and stored for a long time, the loss of active ingredients is also great

Embodiment 1

[0013] The freshly collected Artemisia annua herbs were cleaned, rinsed with water, cut into 2cm-long sections, squeezed with a press while fresh, and filtered with a 100-mesh sieve. Add 2 times the amount of drinking water to the obtained dregs, stir for 20 minutes, let stand for 30 minutes, absorb the supernatant and filter to obtain medicinal juice. The medicinal dregs are squeezed with a press, and the medicinal juice is filtered. Combine the Artemisia annua juice obtained by the above three times of filtration, concentrate under reduced pressure, and set the temperature at 65°C. When the relative density of the concentrated extract is 1.15, it is transferred to a vacuum drying oven and dried at 60°C for 5 hours, and the moisture content is not higher than 10%.

Embodiment 2

[0015] The freshly collected Artemisia annua herbs were cleaned, rinsed with water, cut into 5cm long sections, squeezed with a press while fresh, and filtered with an 80-mesh sieve. Add 3 times the amount of drinking water to the obtained dregs, stir for 30 minutes, let stand for 60 minutes, absorb the supernatant and filter to obtain medicinal juice. The medicinal dregs are squeezed with a press, and the medicinal juice is filtered. Combine the Artemisia annua juice obtained by the above three times of filtration, concentrate under reduced pressure, and set the temperature at 60°C. When the relative density of the concentrated extract is 1.20, it is transferred to a vacuum drying oven and dried at 60°C for 8 hours, and the moisture content is not higher than 12%.

Abstract

The invention discloses freshly squeezed artemisia apiacea vacuum-dried powder decoction pieces and a preparation technology thereof. The technology comprises the following steps: collecting the medicinal material artemisia apiacea and selecting and drip-washing; squeezing when the artemisia apiacea is fresh, and filtering and fetching the juice; adding water into the residue and stirring; filtering and squeezing; and merging the obtained juice and performing decompressed concentration and vacuum drying. In the artemisia apiacea powder decoction pieces prepared by the method, polar and nonpolar active ingredients in the medicinal material are maintained to the greatest degree. The decoction pieces are convenient to store, transport and adjust, the quality is controllable, the curative effect is reliable, and the decoction pieces are of great significance to guaranteeing the clinical effect of traditional Chinese medicines. The popularization and implementation of the method bring remarkable social significance and economic benefits.

Description

technical field [0001] The invention belongs to the field of processing Chinese medicinal materials, and in particular relates to a processing technology of Chinese medicinal artemisia annua decoction pieces. Background technique [0002] Artemisia annua, a traditional Chinese medicine, is Artemisia annua Artemisia annua Dry aerial parts of L. This product is harvested at the flower bud stage, and has the effects of clearing heat and relieving summer heat, removing steam, and cutting off malaria. Clinically, it is often used for fever caused by summer heat, fever caused by yin deficiency, night heat and morning coolness, bone steaming and labor heat, malaria cold and heat, damp heat jaundice, etc. [0003] The commonly used processing methods of Artemisia annua decoction pieces are: cutting the aboveground parts, chopping them up, and drying them for medicine; or sorting and drying them, then packaging them for storage and transportation. After these dried Artemisia annua...
