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 loquat leaf 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 loquat leaves, cut them into 1cm-wide slices, add 0.5 times the weight of the medicinal materials in water, stir for 15 minutes, squeeze them while fresh, collect the virgin medicinal juice, add 5 times the amount of water to the dregs, Stir for 5 minutes, squeeze to extract the juice, add 3 times the amount of water to the remaining medicinal residues, squeeze to extract the juice, combine the first squeezed medicinal juice and the last two squeezed medicinal juices, and filter through a 200-mesh sieve to obtain the loquat leaf medicinal juice. The loquat leaf medicinal juice 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, collect the spray-dried matter, crush it at low temperature, pass through an 80-mesh sieve, and pack it into a bag with a moisture conten...

Embodiment 2

[0014] Wash the freshly collected loquat leaf herbs, cut them into 2cm wide pieces, add 1 times the weight of the herbs in water, stir for 30 minutes, squeeze them while they are fresh, collect the virgin juice, add 3 times the amount of water to the dregs, Stir for 10 minutes, squeeze to extract the juice, add 3 times the amount of water to the remaining medicinal residues, squeeze to extract the juice, combine the first squeezed medicinal juice and the last two squeezed medicinal juices, and filter through a 200-mesh sieve to obtain the loquat leaf medicinal juice. The loquat leaf medicinal juice was concentrated under reduced pressure, and the temperature was set at 70°C. When the relative density of the concentrated extract is 1.10, spray dry, the temperature of the air inlet is 120°C, and the temperature of the air outlet is 90°C, collect the spray-dried matter, crush it at low temperature, pass through a 60-mesh sieve, and the moisture content is not higher than 12%, and ...

Abstract

The invention discloses a preparation method of a loquat leaf fresh-squeezed spray-dried powdery decoction piece. The preparation method comprises loquat leaf harvest, cleaning and selection, leaching, fresh-squeezing, drug juice filtration, mixing of drug dregs and water, drug dreg filtration and squeezing, drug juice mixing, reduced pressure concentration, spray drying, collection of the spray-dried product, crushing, and vacuum packaging. The loquat leaf fresh-squeezed spray-dried powdery decoction piece maximally retains polar and non-polar active ingredients of drugs, is easy to transport, store and blend, has controllable quality and reliable effects and has a significant meaning for guaranteeing the clinical efficacy of traditional Chinese medicine. The promotion and implementation of the preparation method produce prominent social significance 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 loquat leaf decoction pieces of traditional Chinese medicine. Background technique [0002] The traditional Chinese medicine loquat leaf is the loquat tree of the Rosaceae plant Eriobotrya japonica Leaves of Thunb. This product has the effects of clearing the lung and relieving cough, lowering adverse flow and relieving vomiting, harmonizing stomach and diuresis, and relieving cough. It can be used to treat cough due to lung heat, shortness of breath due to adverse Qi, vomiting due to stomach heat, nausea, dry mouth and thirst. [0003] The commonly used processing methods of loquat leaf decoction pieces are as follows: after harvesting, impurities are removed, dried in the sun, packaged for storage and transportation. Go to the decoction piece factory to wash, shred and dry. Such decoction pieces are bu...
