Examples
Embodiment 1
[0037] Prescription: 100g of ginseng, 200g of Ophiopogon japonicus, 100g of schisandra, 100g of microcrystalline cellulose, hollow capsules
[0038] 65% ethanol solution
[0039] Preparation method:
[0040] The process route is as follows
[0041]
[0042] The ginseng, Ophiopogon and Schisandra are washed, crushed, and soaked in a 65% ethanol solution for 24 hours, and then subjected to wet treatment. The extract is spray-dried at 5-7 ml / min to obtain a dry powder of the medicine. Put the microcrystalline cellulose and the drug dry powder into a coating pan with a rotation speed of 15 r / min, and obtain 500 g of dry pellets at 40° C. and 10 r / min. Put it into capsules to get 1000 capsules.
[0043] After testing, it contains ginsenoside Rg 1 The total content of Re is 0.25%, the total content of Ophiopogon saponins B and D accounts for 0.25%, and the content of Schisandrin A accounts for 0.30%.
Embodiment 2
[0045] Prescription: 100g ginseng, 200g Ophiopogon japonicus, 100g schisandra, 120g hypromellose, hollow capsule, 65% ethanol solution
[0046] Preparation method:
[0047] The process route is as follows
[0048]
[0049] The ginseng, Ophiopogon and Schisandra are washed, crushed, soaked in a 65% ethanol solution for 24 hours and then subjected to wet treatment to obtain an extract. Put the hypromellose into the coating pan, spray the extract at a rate of 5-7ml / min at 40°C, and dry 500g of skeleton-shaped pellets. Put it into capsules to get 1000 capsules.
[0050] After testing, it contains ginsenoside Rg 1 The total content of Re accounted for 0.25%, the total content of Ophiopogon saponins B and D accounted for 0.35%, and the content of Schisandrin A accounted for 0.30%.
Embodiment 3
[0052] Using the process of preparing the matrix pellets in Example 1 or 2, different sustained-release materials such as methyl cellulose (MC), hypromellose (HPMC), povidone (PVP), ethyl cellulose, cellulose acetate , Polymethacrylate 80-100g, prepare 500g skeleton-shaped pellets, and then put them into capsules to obtain 1000 capsules. The test results are basically the same as those of Examples 1 and 2.
