Embodiment 1
[0098] Formula: Salvia miltiorrhiza 82.87%, Panax notoginseng 16.21%, Borneol 0.92%.
[0099] Preparation:
[0100] Step 1: Boil Danshen and Panax notoginseng with 8 times the weight of water to extract twice, the first time is 2 hours, the second time is 1 hour, and the extracts are mixed.
[0101] Step 2: Concentrate the extract, add ethanol until the alcohol content of the liquid is 65%, let it stand for 24 hours, recover the ethanol from the supernatant, and concentrate at normal pressure to form an extract.
[0102] Step 3, the extract and borneol are used as the active ingredient of the medicine, the matrix is a eutectic mixture of xylitol and starch, and the feeding ratio is: extract medicine: matrix=1:5.5, add borneol, liquid paraffin is the condensing agent, and the medicine The temperature is 90° C., the materialization time is 1.5 hours, the condensate temperature is 1° C., the drop distance is 7 cm, and the drop speed is 35 drops per minute to prepare drop pills...
Embodiment 2
[0104] Recipe: Salvia 20%, Panax notoginseng 79%, Borneol 1%.
[0105] Step 1: Extracting Danshen and Panax notoginseng with 2 times the weight of water, the number of extractions is 2 times, each extraction is 1 hour, and the extracts are mixed.
[0106] In step 2, the extract is concentrated, and ethanol is added until the alcohol content of the liquid is 60%, and left to stand for 12 hours. The ethanol is recovered from the supernatant, and concentrated into an extract.
[0107] Step 3, use step 2 extract and borneol together as pharmaceutical active ingredient, substrate is eutectic mixture of xylitol and starch, feed ratio is: extract medicine: substrate=1: 3, add borneol, liquid paraffin is condensing agent , the drug temperature is 85°C, the material time is 1 hour, the condensate temperature is -2°C, the drop distance is 5cm, and the drop rate is 30 drops per minute.
Embodiment 3
[0109] Formula: Salvia 97%, Panax notoginseng 2%, Borneol 1.0%.
[0110] In step 1, the salvia miltiorrhiza and notoginseng are extracted with 12 times the weight of water, the number of extractions is 2 times, each extraction is 1 hour, and the extracts are mixed.
[0111] In step 2, the extract is concentrated, ethanol is added until the alcohol content of the medicinal solution is 70%, and it is left to stand for 12 hours. The supernatant is recovered with ethanol, concentrated into an extract or dried.
[0112] Step 3, use step 2 extract and borneol together as the active ingredient of the medicine, the substrate is a eutectic mixture of xylitol and starch, and the feeding ratio is: extract medicine: substrate=1:7, add borneol, and liquid paraffin is the condensing agent , the drug temperature is 95°C, the time of chemical change is 2 hours, the temperature of the condensate is 4°C, the drop distance is 10cm, and the drop speed is 45 drops per minute.
