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 Gynostemma pentaphylla medicinal material used for extraction is also dried and stored for a long time, the loss of active ingredients is also very large

Embodiment 1

[0012] Wash the freshly collected Gynostemma pentaphylla medicinal material, cut it into 1cm-long sections, add water 0.5 times the weight of the medicinal material, stir for 15 minutes, and squeeze the juice while it is fresh. Add 2 times the amount of tap water to the obtained medicinal dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract the juice. The obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the gynostemma medicinal juice of the above three times, filter with a 60-mesh sieve, concentrate the filtrate under reduced pressure, and set the temperature at 60°C. When the relative density of the concentrated extract was 1.10, it was transferred to a -20°C refrigerator and frozen for 12 hours. Freeze drying was carried out after taking out the frozen material, the temperature was set at -18°C, the pressure was 0.09Mpa, and the time was 24 hours. Collect the freeze-dried product, pulverize...

Embodiment 2

[0014] Wash the freshly collected Gynostemma pentaphyllum medicinal material, cut it into 2cm long sections, add 1 times the weight of the medicinal material in water, stir for 30 minutes, and squeeze out the 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 obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the above 3 times of Gynostemma pentaphyllum medicinal juice, filter with a 100-mesh sieve, concentrate the filtrate under reduced pressure, and set the temperature at 70°C. When the relative density of the obtained concentrated extract was 1.05, it was transferred to a -20°C refrigerator and frozen for 8 hours. Freeze-dry after taking out the frozen material, the temperature is set at -40°C, the pressure is 0.09Mpa, and the time is 48 hours. Collect the freeze-dried product, pulverize it, pass th...

Abstract

The invention discloses a preparation technology for a freshly squeezed freeze drying gynostemma pentaphylla powder decoction piece. The preparation technology comprises the following steps: harvesting gynostemma pentaphylla medicinal material, selecting, cleaning, freshly squeezing and leaching decoction juice; adding water into decoction dregs, stirring, filtering and squeezing; mixing the acquired decoction juice and then reducing pressure and freeze-drying. The gynostemma pentaphylla powder decoction piece prepared according to the method is capable of extremely reserving the polar and non-polar active ingredients in the medicinal material; the decoction piece is beneficial to storage and transportation, is convenient for regulating, is in controllable quality, has reliable curative effect and has significance in guaranteeing the clinic curative effect of the traditional Chinese medicine; the popularization and implementation of the method have obvious social significance and economic benefit.

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 gynostemma pentaphyllum decoction pieces. Background technique [0002] Gynostemma Gynostemma Gynostemma pentaphyllum (Thunb.) The aerial part of Makino. It has the effects of replenishing qi, calming the nerves, lowering blood pressure, clearing heat and detoxifying, relieving cough and eliminating phlegm. [0003] Commonly used Gynostemma pentaphyllum decoction pieces are processed as follows: remove impurities after harvesting, dry in the sun, and pack directly for storage and transportation. The hygienic indicators of these dried Gynostemma pentaphyllum cannot reach the standard, and the medicinal material is prone to mildew, which leads to the decline of the quality of the medicinal material and the reduction of the clinical curative effect. Such herbal medicine pieces are bulky, prone to deteri...
