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 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] Clean the freshly collected Gynostemma pentaphylla, 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 Gynostemma pentaphyllum medicinal material, wash it with water to remove the sediment, cut it 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 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 technology for a freshly squeezed vacuum 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, concentrating, performing vacuum drying, crushing and then performing vacuum packaging. 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...
