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

Embodiment 1

[0011] The freshly collected Folium Folium medicinal material is net-selected, washed with water to remove sediment, squeezed with a press to extract juice while fresh, and retaining 1% by weight of the virgin medicinal juice for another use. 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 remaining first-pressed medicinal juice is combined with the subsequent two squeezed medicinal juices, 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 1.05, it is spray-dried, the air inlet temperature is 140°C, and the air outlet temperature is 100°C. The spray-dried matter is collected, crushed at low temperature, and passed through an 80-mesh sieve. Mix this ...

Embodiment 2

[0013] The freshly collected Folium Folium medicinal material is cleaned, washed with water to remove sediment, squeezed with a press to extract juice while fresh, and retaining 5% by weight of the virgin medicinal juice for another use. 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 remaining first-pressed medicinal juice is combined with the subsequent two squeezed medicinal juices, and filtered with a 100-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 1.10, it is spray-dried, the air inlet temperature is 120°C, and the air outlet temperature is 90°C. The spray-dried matter is collected, crushed at low temperature, and passed through an 80-mesh sieve. Mix this spray-...

Abstract

The invention discloses freshly squeezed and spray-dried granule decoction pieces of Folium folium and a preparation process thereof. In this process, after the Folium Folium medicinal material is harvested, it is cleaned, rinsed, squeezed while it is fresh, and the medicinal juice is filtered. The dregs are added with water, stirred, filtered and pressed. The obtained medicinal juices are combined, concentrated under reduced pressure, spray-dried, and the spray-dried product is collected, crushed and mixed with virgin medicinal juice to granulate, granulated and then vacuum-packed. The Folium Folium granule decoction pieces prepared by this method retain the polar and non-polar active ingredients in the medicinal material to the greatest extent. Granular decoction pieces have good fluidity, which is 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 for decoction pieces of the traditional Chinese medicinal Folium Folium. Background technique [0002] The traditional Chinese medicine Daqingye is the cruciferous plant Isatis indigo Isatis indigotica Dry leaves of Fort. Harvest in 2~3 times in summer and autumn, remove impurities and dry in the sun. This product has the effects of clearing away heat and detoxifying, cooling blood and eliminating spots. It is mainly used for the treatment of febrile diseases with high fever and polydipsia, coma, rash, vomiting blood, epistaxis, dysentery, erysipelas, aphtha, mumps, and sore throat. [0003] The commonly used processing methods of Folium Folium decoction pieces are: harvest in summer and autumn, remove impurities, dry in the sun, and pack for storage and transportation. Such herbal decoction pieces are bulky,...
