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

Embodiment 1

[0012] Wash the freshly collected geranium medicinal material, cut into 1cm sections, add water 0.5 times the weight of the medicinal material, stir for 15 minutes, squeeze while fresh, and collect the virgin medicinal juice. Add 3 times the amount of tap water to the obtained dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract the juice. The remaining medicinal dregs are squeezed with a press to extract the juice. The above-mentioned 3 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 was 1.15, the extract was frozen in a -80°C refrigerator for 6 hours. Take out the east knot, freeze-dry, the pressure is 0.09Mpa, the temperature is -20 ℃, dry for 24 hours. Take out the freeze-dried product, crush it at low temperature, pass through an 80-mesh sieve, the moisture content is not higher th...

Embodiment 2

[0014] Wash the freshly collected geranium medicinal material, cut it into 2cm sections, add 1 times the weight of the medicinal material in water, stir for 30 minutes, squeeze it while it is fresh, and collect the virgin medicinal juice. Add 5 times the amount of tap water to the obtained dregs, stir for 30 minutes, and press with a plate-and-frame filter press to extract the juice. The remaining medicinal dregs are squeezed with a press to extract the juice. The above-mentioned 3 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 was 1.10, the extract was frozen in a -80°C refrigerator for 8 hours. Take out the east knot, freeze-dry, the pressure is 0.08Mpa, the temperature is -40 ℃, dry for 48 hours. Take out the freeze-dried product, crush it at low temperature, pass through a 60-mesh sieve, the moisture content is n...

Abstract

The invention discloses a preparation process of a herba geranium wilfordii fresh squeezing freeze-drying powder decoction piece. According to the process, after the medicinal materials of herba geranium wilfordii are harvested, clean sorting, rinsing and segment cutting are performed; squeezing is performed when the herba geranium wilfordii is fresh; medicine juice is filtered and taken; water is added into medicine slag; stirring is performed; filtering and squeezing are performed; the obtained medicine juice is merged and is then subjected to reduced pressure concentration and freeze drying; freeze-drying products are collected; after the crushing, vacuum packaging is performed. The herba geranium wilfordii fresh squeezing freeze-drying powder decoction piece prepared by the method has the advantages that polar and nonpolar active ingredients in the medicinal materials are simultaneously remained to the maximum degree; the decoction piece is favorable for storage and transportation; the proportioning is convenient; the quality is controllable; the curative effect is reliable; the important significance is realized on guaranteeing the clinic curative effect of traditional Chinese medicine. After the popularization and the implementation of the method, the obvious social significance and economic benefits can be realized.

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 traditional Chinese medicine geranium. Background technique [0002] The traditional Chinese medicine geranium is the dry aboveground part of geranium, geranium, etc. This product has the effects of expelling wind, promoting blood circulation, clearing heat and detoxifying, and is clinically used to treat rheumatism pain, spasm and numbness, traumatic injuries, enteritis, dysentery, etc. [0003] The commonly used processing methods of geranium decoction pieces are: harvesting in summer and autumn, removing impurities, drying in the sun, and then packaging for storage and transportation. Such herbal decoction pieces are bulky, have poor hygienic indicators, are prone to pollution and mildew, and are difficult to guarantee quality, which is not conducive to formula adjustment and clinical ...
