[0054] Preparation method of compound motherwort mixture
[0055] 1) Extraction of active ingredients of Motherwort: Atmospheric pressure microwave-assisted extraction.
[0056] ① Crush the motherwort to 2~ 10 mm particle size, immerse in water for 2 hours, filter out the water, add cyclohexane-ethanol mixed solvent, and use atmospheric pressure microwave-assisted extraction (microwave wavelength 1mm-1m, frequency 300-300000MHZ). The extraction time was 15 min.
[0057] ② Separate and remove the medicinal residues to obtain an extract, and vacuum concentrate the extract below 60°C to an extract with a relative density of 1.21-1.25, then add invert sugar, mix well, and concentrate in vacuum to obtain a dry extract.
[0058] ③Using the airflow ultrafine pulverization method, the dried motherwort extract was pulverized, and the particle size ≤ 20 μm.
[0059] 2) Extraction of active components of Radix Astragali: Atmospheric pressure microwave-assisted extraction.

[0065] Experimental study on the comparison between microwave-assisted extraction technology and traditional extraction method
[0066] Microwave-assisted extraction technology has enhanced heat transfer and mass transfer on the basis of traditional extraction technology. The experiment shows that microwave extraction technology has high extraction efficiency, good reproducibility, less solvent consumption, simple equipment, easy operation, sufficient extraction and less pollution. Etc.
[0067] The application of microwave-assisted extraction technology to the active ingredients of Chinese herbal medicine and the extraction of active substances in plant cells is a new application field. The experimental results of microwave-assisted extraction technology compared with traditional extraction methods are shown in the table below.

[0071] Dissolution Determination of Compound Motherwort Tablets
[0072] The particle size and surface area of the drug are important factors affecting the dissolution rate of solid oral preparations. For the same weight of the drug, the smaller the particle size, the larger the surface area, the better the dissolution.
[0073] 1. For the dissolution test of compound motherwort tablets, two samples of different preparation methods of dry extract were selected:
[0074] 1) Atmospheric pressure microwave-assisted extraction to extract the active ingredients of motherwort and astragalus → vacuum concentration and vacuum drying to obtain dry extracts → use airflow ultrafine grinding method to crush the dry extracts of motherwort and dry extracts of astragalus into ultrafine powder, particle size ≤ 20 μm .
[0075] 2) Soak the chopped motherwort and astragalus in water → decoct and extract with water for 3 times to obtain the extract → vacuum concentrate, vacuum dry, crush and ...
