[0028] A preparation method of fruit-like Chinese medicinal material free decoction, comprising the following steps:
[0029] 1) Pick up the fruit-like Chinese medicinal materials, remove impurities, and dry;
[0030] 2) Grinding the dried Chinese medicinal materials into fine powder of Chinese medicinal materials with a particle size of 100-150 μm with an ultrafine pulverizer;
[0031] 3) Put the fine powder of Chinese medicinal materials obtained in step 2) into supercritical CO 2 Extraction is carried out in the extraction device, and then enters the separation tank for separation to obtain extracts and medicinal residues;
[0032] 4) Add 10 to 20 times the volume of water to the dregs obtained in step 3), soak for 60 to 120 minutes at 40 to 50°C, then add 0.3% to 0.8% of the dregs weight of cellulase and 0.1 %~0.5% pectinase for enzymolysis, ultrasonic assisted treatment, to obtain the extract;
[0033] 5) Combine the extract obtained in step 3) and the extract obtained...

[0044] Taking Cornus officinalis as an example, the preparation method of its decoction-free preparation comprises the following steps:
[0045] 1) Pick up the dogwood, remove impurities, and dry;
[0046] 2) Grinding the dried Cornus officinalis with an ultrafine pulverizer into fine powder of Cornus officinalis with a particle size of 100-150 μm;
[0047] 3) Put the dogwood fine powder obtained in step 2) into supercritical CO 2 Extraction is carried out in the extraction device, the extraction temperature is 40°C, the pressure is 30MPa, CO 2 The flow rate is 12L / min, the extraction time is 2h, and then it enters the separation tank for separation to obtain the extract and dregs;
[0048] 4) Add 10 times the volume of water to the medicinal dregs obtained in step 3), soak for 60 minutes at 40°C, then add 0.3% of the weight of medicinal dregs to obtain an enzyme activity of 1×10 4 U / g cellulase and 0.1% enzyme activity is 1×10 4 U / g of pectinase, enzymatic hydrolysis for ...
Embodiment 2
[0052] Taking Ligustrum lucidum as an example, the preparation method of its decoction-free preparation comprises the following steps:
[0053] 1) Pick up the privet fruit, remove impurities, and dry;
[0054] 2) Grinding the dried Ligustrum lucidum into a fine powder of Ligustrum lucidum with a particle size of 100-150 μm with an ultrafine pulverizer;
[0055] 3) Put the Ligustrum lucidum fine powder obtained in step 2) into supercritical CO 2 Extraction is carried out in the extraction device, the extraction temperature is 43°C, the pressure is 31MPa, CO 2 The flow rate is 13L / min, the extraction time is 2.5h, and then it enters the separation tank for separation to obtain the extract and dregs;
[0056] 4) Add 13 times the volume of water to the dregs obtained in step 3), soak at 43°C for 70 minutes, then add 0.5% of the dregs by weight, and the enzyme activity is 1×10 4 U / g cellulase and 0.2% enzyme activity is 1×10 4 U / g of pectinase, enzymatic hydrolysis for 120 minu...
