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 mulberry leaf medicinal materials used for extraction are also dried and stored for a long time, the loss of active ingredients is also great

Embodiment 1

[0012] Wash the freshly collected mulberry leaf herbs, cut them into 1cm wide slices, add 0.5 times the weight of the herbs in water, stir for 15 minutes, and squeeze the juice while it is fresh. 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, the extract was frozen in a -80°C refrigerator for 6 hours. Take out the east knot, freeze-dry, the pressure is 0.09Mpa, the temperature is -20 ℃, dry for 24 hours. Take out the freeze-dried product, crush it at low temperature, pass through an 80-mesh sieve, the moisture content is not higher than 12%, pack it into a bag, 1k...

Embodiment 2

[0014] Wash the freshly collected mulberry leaf herbs, cut them into 2cm wide slices, add 1 times the weight of the herbs in water, stir for 30 minutes, and squeeze 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 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, the extract was frozen in a -80°C refrigerator for 8 hours. Take out the east knot, freeze-dry, the pressure is 0.08Mpa, the temperature is -40 ℃, dry for 48 hours. Take out the freeze-dried product, crush it at low temperature, pass through a 60-mesh sieve, the moisture content is not higher than 12%, bag it, 1kg / bag, add the ...

Abstract

The invention discloses a process for preparing mulberry leaf freshly squeezed lyophilized powder decoction pieces. The process comprises the following steps: collecting a mulberry leaf medicinal material, washing and leaching, squeezing when the mulberry leaf is fresh, and filtering to obtain decoction; stirring the decoction dregs with water, filtering and squeezing; and mixing decoctions, concentrating at reduced pressure, lyophilizing, collecting a lyophilized product, grinding and packaging in vacuum. According to the mulberry leaf powder decoction pieces, polar and non-polar effective ingredients in the medicinal material can be furthest maintained at the same time. The decoction pieces are convenient to store, transport and regulate, has controllable quality and reliable curative effect, and has an important meaning to guarantee of clinical curative effect of traditional Chinese medicines. Application and implementation of the method have remarkable social meaning and economic benefit.

Description

technical field [0001] The invention belongs to the field of processing traditional Chinese medicinal materials, in particular to a processing technology of traditional Chinese medicine mulberry leaf decoction pieces. Background technique [0002] The traditional Chinese medicine mulberry leaf is the moraceae plant mulberry Morus alba Dried leaves of L. This product has the functions of dispelling wind and clearing heat, clearing liver and improving eyesight, clearing lung and relieving cough, etc. [0003] The commonly used processing method of mulberry leaf decoction pieces is as follows: after the first frost, the mulberry leaves are harvested, impurities are removed, dried in the sun, and then packaged for storage and transportation. Such decoction pieces are bulky, have poor hygienic indicators, are prone to pollution and mildew, and are difficult to guarantee quality, which is not conducive to formula adjustment and clinical efficacy, and even brings hidden harm to p...
