Embodiment 1
[0042] What present embodiment enumerates is Radix Bupleuri granule 350g, and formula is as follows:
[0043] Active ingredients: Bupleurum volatile oil 3ml; saikosaponin 6g;
[0044]Pharmaceutical excipients: 30g of β-CD, 256g of sucrose, 64g of dextrin, appropriate amount of starch slurry.
[0045] Preparation Process:
[0046] (1) Take 1000g of Bupleurum medicinal material, crush it to 20-60 mesh, and extract the volatile oil of Bupleurum with carbon dioxide supercritical extraction equipment:
[0047] Put the pulverized Bupleuri herb into the extraction kettle, and then pump the supercritical medical grade carbon dioxide fluid through the purifier, cooling system and high-pressure pump into the extraction kettle at a flow rate of about 20kg / h. Extraction under the condition of 20MPa pressure for 1.5h; two-stage separation of the extract, the operating conditions of the separation tank I are: pressure 12MPa, temperature 40°C, the operating conditions of the separation tan...
Embodiment 2
[0052] What present embodiment enumerates is Bupleurum nose drops 1000ml, and formula is as follows:
[0053] Active ingredients: Bupleurum volatile oil 1ml; saikosaponin 10g;
[0054] Pharmaceutical excipients: HP-β-CD 30g, sodium chloride 9g.
[0055] Preparation Process:
[0056] (1) Take 1000g of Bupleuri herb, crush it to 20-60 mesh, add 10 times the amount of water, soak at 70°C for 8 hours, distill, and collect volatile oil, about 1ml;
[0057] (2) Take the medicinal residues of Bupleurum chinensis after supercritical extraction of volatile oil, add 65% (v / v) of 12 times the volume of the medicinal material, and soak in ethanol with a pH value of 8 for 24 hours, and perform percolation at a flow rate of 10mL / min. The percolate is concentrated under reduced pressure at 65°C to a concentrated solution with a relative density of 1.1 to 1.2;
[0058] Put the concentrated solution on a D101 macroporous resin column with a diameter-to-height ratio of 1:3 for static adsorpt...
Embodiment 3
[0063] What present embodiment enumerates is Bupleurum oral liquid 1000ml, and formula is as follows:
[0064] Active ingredients: Bupleurum volatile oil 4ml; saikosaponin 4g;
[0065] Pharmaceutical excipients: HP-β-CD 50g, aspartame 2g.
[0066] Preparation Process:
[0067] (1) Take 1000g of Bupleurum medicinal material, crush it to 20-60 mesh, and extract the volatile oil of Bupleurum with carbon dioxide supercritical extraction equipment: the extraction process is the same as in Example 1, wherein the flow rate of the supercritical medical grade carbon dioxide fluid is 20kg / h, The extraction conditions are: 35°C, 25MPa, and the extraction time is 1h. The operating conditions of the separation tank I are: the pressure is 12MPa, the temperature is 35°C, the operating conditions of the separation tank II are: the pressure is 6MPa, the temperature is 30°C; The supercritical product with Bupleurum volatile oil as the main component was collected at the outlet of the fraction...
