preparation example Construction

[0037] The preparation method of Duhuo traditional Chinese medicine formula granule of the present invention comprises the following steps:

[0038] Take lovage herb powder and extract it with supercritical carbon dioxide to prepare lovage extract and medicinal residue;

[0039] Using excipients to absorb the lovage extract to prepare lovage extract powder;

[0040] Adding water to the medicinal dregs, decocting, concentrating the obtained extract and adding auxiliary materials to prepare the dry extract powder of chrysalis;

[0041] Mixing the Lok Huo extract powder and the Lok Huo dry extract powder to prepare Lok Huo traditional Chinese medicine formula granules;

[0042] The excipient is selected from one or more of silicon dioxide, magnesium aluminum silicate and kaolin, and the particle size of the excipient is 1 μm to 200 μm.

[0043] Understandably, the lovage medicinal material is purified and crushed into a raw material powder with a particle size of 10-60 mesh to ...

Embodiment 1

[0136] This embodiment provides a kind of Duhuo traditional Chinese medicine formula granule and its preparation method, such as Figure 6 As shown, the specific steps are as follows:

[0137] Take 1000 g of the lovage medicinal material, remove impurities, and crush it into a 10-mesh lovage medicinal material powder with an average particle diameter. Send the lovage herb powder into a supercritical extraction kettle, use ethanol as an entrainer, input carbon dioxide fluid into the kettle, extract at an extraction pressure of 35MPa, and an extraction temperature of 65°C for an extraction time of 1.0 hour, and then extract the carbon dioxide in the extraction kettle The fluid is introduced into a supercritical separation kettle, and separated at a separation pressure of 10 MPa and a separation temperature of 60° C. for a separation time of 1.0 hour. The carbon dioxide is separated to obtain 27.2 g of a semi-solid oily cloaca extract and about 972 g of medicinal residues.

Embodiment 2

[0149] This example provides a solitary traditional Chinese medicine formula granule and its preparation method, the preparation method of which is basically the same as that of Example 1, the only difference is that the excipient is silicon dioxide with a particle size of 1 μm to 100 μm, and the specific steps are as follows:

[0150] Take 1000 g of the lovage medicinal material, remove impurities, and crush it into a 10-mesh lovage medicinal material powder with an average particle diameter. Send the lovage herb powder into a supercritical extraction kettle, use ethanol as an entrainer, input carbon dioxide fluid into the kettle, extract at an extraction pressure of 35MPa, and an extraction temperature of 65°C for an extraction time of 1.0 hour, and then extract the carbon dioxide in the extraction kettle The fluid is introduced into a supercritical separation kettle, and separated at a separation pressure of 10 MPa and a separation temperature of 60° C. for a separation time...

Abstract

The invention relates to radix angelica pubescens traditional Chinese medicine formula granules and a preparation method thereof. The preparation method comprises the following steps of taking radix angelica pubescens medicinal material powder, and performing supercritical carbon dioxide extraction to prepare a radix angelica pubescens extract and medicine residues; adsorbing the radix angelica pubescens extract by adopting an excipient to prepare radix angelica pubescens extract powder; adding water into the medicine residues, performing decocting, concentrating the obtained extracting solution, and adding auxiliary materials to prepare radix angelica pubescens dry extract powder; and mixing the radix angelica pubescens extract powder with the radix angelica pubescens dry extract powder to prepare the radix angelica pubescens traditional Chinese medicine formula granules, wherein the excipient is selected from one or more of silicon dioxide, magnesium aluminum silicate and kaolin, andthe particle size of the excipient is 1-200 [mu]m. According to the preparation method, fat-soluble components and water extracts are combined, so that full-component extraction and retention of theradix angelica pubescens medicinal material are truly realized, and the content of effective components is increased.

Description

technical field [0001] The invention relates to the field of preparation of traditional Chinese medicine preparations, in particular to Duhuo traditional Chinese medicine formula granules and a preparation method thereof. Background technique [0002] The solitary life is the dried root of Angelica pubescens Maxim.f.biserrata Shanet Yuan, a plant of the Umbelliferae family. It has the effects of expelling wind and dampness, clearing numbness and relieving pain. Modern research has found that the main components of lovage include volatile oils, coumarins, sterols, and sugars, which have anti-inflammatory, analgesic, and platelet aggregation-inhibiting effects. Inflammation and so on. In the clinical practice of TCM, Duhuo is mainly used in compound decoctions, such as Duhuo Jisheng Decoction, Duhuo Gegen Decoction, etc. However, the traditional decoction has many inconveniences such as inconvenient decoction, time-consuming and laborious, and it is difficult to meet the nee...
