Problems solved by technology

The preparation process of granular decoction pieces, the extraction is not only time-consuming and energy-consuming, but also because a large amount of 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 extracting herb is also dried and stored for a long time, the loss of active ingredients is also great

Embodiment 1

[0012] Clean the freshly collected herbaceous herb, wash it with water to remove the sediment, cut it into 1cm sections, add 1 times the amount of water, stir for 5 minutes, and squeeze it with a press to extract the juice while it is fresh. Add 5 times the amount of water to the obtained dregs, stir for 20 minutes, and squeeze to extract the juice. The above 2 concoctions were combined and filtered with a 100-mesh sieve. The filtrate was concentrated under reduced pressure and the temperature was set at 65 °C. When the relative density of the concentrated extract is 1.10, it is transferred to a vacuum drying oven, dried at 75°C for 48 hours, crushed at low temperature, and the moisture content is not higher than 12%.

Embodiment 2

[0014] Clean the freshly collected herbal medicine, wash with water to remove the silt, cut into 2cm sections, add 2 times the amount of water, stir for 10 minutes, and squeeze it with a press to extract the juice while it is still fresh. Add 10 times the amount of water to the obtained dregs, stir for 30 minutes, and squeeze to extract the juice. The above 2 concoctions were combined and filtered with an 80-mesh sieve. The filtrate was concentrated under reduced pressure and the temperature was set at 70 °C. When the relative density of the concentrated extract is 1.15, it is transferred to a vacuum drying oven, dried at 70°C for 72 hours, crushed at low temperature, and the moisture content is not higher than 12%.

Abstract

The invention discloses a preparation process of a herba speranskiae tuberculatae powder decoction piece obtained through freshly squeezing and vacuum drying. According to the process, the medicinal material, namely, herba speranskiae tuberculatae is harvested, selected, rinsed and freshly squeezed, and decoction is obtained through filtering; water is added into the dregs of the decoction, stirring is carried out, filtering is carried out, and squeezing is carried out; the decoctions are mixed, reduced pressure concentration is carried out, vacuum drying is carried out, grinding is carried out, and vacuum packaging is carried out. For the herba speranskiae tuberculatae powder decoction piece prepared by adopting the method, the polar and non-polar active ingredients in the medicinal materials are reserved to the maximum. The decoction piece is easy to store and transport, the dispensing is convenient, the quality is controllable, the curative effects are reliable, and the decoction piece has the great significance for guaranteeing the clinical efficacies of the traditional Chinese medicines. The popularization and implementation of the method have significant social significance and economic efficiency.

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 decoction pieces of the traditional Chinese medicine Sperantosporum. Background technique [0002] The traditional Chinese medicine Sperantosporum is the whole grass of Euphorbiaceae. It has the effects of expelling wind and dampness, promoting blood circulation and relieving pain. [0003] The commonly used processing methods of Speranthes decoction pieces are as follows: after harvesting, impurities are removed, dried in the sun, and directly packaged for storage and transportation. The hygienic indicators of these dried Sperancis can not reach the standard, 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. Such herbal medicine pieces are bulky, prone to deterioration and contamination, and the ...
