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 tangerine leaf 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] Freshly collected tangerine leaf medicinal materials are cleaned, rinsed with water, cut into 1cm wide slices, added with water 0.5 times the weight of the medicinal materials, stirred for 15 minutes, and squeezed while fresh. 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, add 5% NaCl by weight to the orange leaf condensed water collected during concentration under reduced pressure, and stir to dissolve. The solution was placed in an oil-water separator and allowed to stand at ...

Embodiment 2

[0014] Freshly collected tangerine leaf medicinal materials are cleaned, rinsed with water, cut into 2cm wide slices, added with 1 times the weight of medicinal materials in water, stirred for 30 minutes, and squeezed while fresh. 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, add 3% NaCl by weight to the condensed water of orange leaves collected during concentration under reduced pressure, and stir to dissolve. The solution was placed in an oil-water separator and allowed to stand at 10°C ...

Abstract

The invention discloses freshly-squeezed and vacuum-dried decoction powder prepared from folium citri reticulatae and a preparation process of the decoction powder. According to the process, folium citri reticulatae medicinal materials are selected, washed and squeezed while fresh after being harvested, and medicinal juice is obtained through filtration; medicinal residues are mixed with water, filtered and squeezed; the obtained medicinal juice is mixed, concentrated under reduced pressure and subjected to vacuum drying; condensate is concentrated, volatile oil is separated, a product is mixed with a vacuum dried material, and the mixture is sieved and bagged. The decoction powder prepared from folium citri reticulatae with the process keeps effective ingredients in the medicinal materials to the greatest extent. The decoction powder is convenient to store, transport and regulate, controllable in quality and reliable in curative effect and has great significance in guaranteeing the clinical curative effect of traditional Chinese medicines. With popularization and implementation of the process, the decoction powder has remarkable social benefits 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 of Chinese medicinal orange leaf decoction pieces. Background technique [0002] Chinese medicine orange leaf is Rutaceae orange tree Citrus reticulata Dried leaves of Blanco. This product has the effects of soothing the liver, promoting qi circulation, resolving phlegm, and reducing swelling and poison. It can treat hypochondriac pain, lung abscess, hernia and so on. [0003] Commonly used orange leaf decoction pieces are processed as follows: remove impurities after harvesting, dry in the sun, pack for storage and transport. This kind of traditional Chinese medicine decoction pieces is bulky, easy to be polluted and mildewed, has poor hygienic conditions, and is difficult to guarantee the quality, which is not conducive to formula adjustment and ensuring its clinical efficacy. [0004] At present, there a...
