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

[0011] Freshly collected mulberry leaves are selected, washed with water to remove sediment, cut into 1cm wide slices, added with water 0.5 times the weight of the medicinal materials, stirred for 15 minutes, squeezed while fresh, and reserved 0.1% by weight of the virgin medicinal juice Use separately. 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 l...

Embodiment 2

[0013] Freshly collected mulberry leaves are selected, washed with water to remove sediment, cut into 2cm wide slices, added with water of 1 times the weight of the medicinal materials, stirred for 30 minutes, squeezed while fresh, and reserved 0.5% by weight of virgin medicinal juice Use separately. 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 t...

Abstract

The invention discloses a preparation method of a mulberry leaf fresh-squeezed spray-dried granule decoction piece. The preparation method comprises mulberry 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, mixing of the spray-dried product and the primary squeezed drug juice, granulation, granule finishing, and vacuum packaging. The mulberry leaf fresh-squeezed spray-dried granule 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, 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...
