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 verbena 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 verbena herb is selected, washed with water to remove sediment, cut into 3cm sections, and squeezed with a press to extract juice while it is fresh. 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 than 12%, pack it into a bag, 1kg / bag, add the bagged ...

Embodiment 2

[0014] Freshly collected verbena herb is selected, washed with water to remove sediment, cut into 3cm sections, and squeezed with a press to extract juice while it is fresh. 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 not higher than 12%, bag it, 1kg / bag, add the bagged antioxidant a...

Abstract

The invention discloses a freshly squeezed freeze-dried powder decoction piece of verbena and a preparation process thereof. In this process, after the verbena medicinal material is harvested, it is cleaned, rinsed, cut into sections, squeezed while it is fresh, and the medicinal juice is filtered out. The dregs are mixed with water, filtered and pressed. The obtained medicinal juices are combined, concentrated under reduced pressure, freeze-dried, and the freeze-dried product is collected, pulverized and packed in vacuum. Verbena powder decoction pieces prepared by this method retain the polar and non-polar active ingredients in the medicinal material at the same time to the greatest extent. The decoction pieces are convenient for storage and transportation, convenient for dispensing, controllable in quality, and reliable in curative effect, which is of great significance to guarantee the clinical curative effect of traditional Chinese medicine. The popularization and implementation of this Law will have significant social 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 decoction pieces of Chinese medicinal verbena. Background technique [0002] Verbena Verbena Verbena officinalis Dry aerial parts of L. This product has the effects of promoting blood circulation, dispelling blood stasis, detoxifying, promoting diuresis, reducing jaundice, and cutting off malaria. It is used for the treatment of accumulation of lumps, dysmenorrhea, amenorrhea, sore throat, edema, and malaria. [0003] The commonly used processing methods of verbena decoction pieces are: harvesting and cutting when the flowers bloom from June to August, 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...
