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 Hedyotis diffusa 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] The freshly collected Hedyotis diffusa medicinal materials are cleaned, washed with water to remove the sediment, cut into 5cm sections while fresh, and squeezed with a press to extract the 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, it was transferred to a -20°C refrigerator and frozen for 12 hours. The frozen material was taken out and then freeze-dried at a temperature of -20°C, a pressure of 0.09Mpa, and a freeze-drying time of 48 hours. Collect the lyophilized product, pulverize it, sub-package, 1kg / bag, add antioxidant and desiccant in the b...

Embodiment 2

[0014] Clean the freshly collected Hedyotis diffusa medicinal material, wash it with water to remove the sediment, cut it into 10cm sections while it is fresh, and squeeze it with a press to extract the 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, it was transferred to a -80°C refrigerator and frozen for 8 hours. The frozen material was taken out and freeze-dried at a temperature of -30° C., a pressure of 0.08 MPa, and a freeze-drying time of 24 hours. Collect the lyophilized product, pulverize it, sub-package, 1kg / bag, add antioxidant and desiccant in th...

Abstract

The invention discloses freshly squeezed freeze drying spreading hedyotis herb powdery decoction pieces and a preparation process thereof. The process is characterized by harvesting the medicinal material spreading hedyotis herb, then cleaning, selecting and drip-washing spreading hedyotis herb, squeezing spreading hedyotis herb while spreading hedyotis herb is fresh and taking the juice after filtration; adding water to the dregs, stirring the dregs and carrying out filtering and squeezing; mixing the obtained juice and then carrying out vacuum concentration, carrying out freeze drying and carrying out vacuum packaging after grinding. The spreading hedyotis herb powdery decoction pieces prepared by the method furthest retain the polar and nonpolar active ingredients in the medicinal material, are easy to store and transport and convenient to regulate, are controllable in quality, have reliable curative effects and have great significance in guaranteeing the clinical effects of traditional Chinese medicines. Popularization and implementation of the method has remarkable social significance and economic benefits.

Description

technical field [0001] The invention belongs to the field of processing Chinese medicinal materials, and in particular relates to a processing technology for decoction pieces of the traditional Chinese medicine Hedyotis diffusa. Background technique [0002] Hedyotis diffusa Oldenlandia diffusa (Willd.) The dried whole herb of Roxb., bitter, light, cold in nature. This product has the effects of clearing heat and detoxifying, eliminating pain and stagnation, diuresis and dehumidification. It can be used to treat asthma and cough due to lung heat, sore throat, intestinal fistula, boils, sores, poisonous snake bites, hot stranguria, dysentery, enteritis and other diseases. [0003] The commonly used processing method of Hedyotis diffusa decoction pieces is as follows: after harvesting the whole herb, remove impurities, wash the sediment, dry it in the sun, and then pack it for storage and transportation. Such herbal decoction pieces are bulky, easily polluted and moldy, and...
