experiment example 1
[0077] Experimental example 1. The preferred experiment of the preparation process of the traditional Chinese medicine composition of the present invention
[0078] 1. Research on extraction process
[0079] 1.1 Research on the amount of water added for water extraction: In the original extraction process, the volume of the solvent added was not specified, but in the actual production process, the volume of the extraction solvent added is an important parameter, which has a great impact on the quality of the extracted extract, so it is researched During the process, the original extraction process was perfected to ensure the scientificity and controllability of the extraction process.
[0080] According to the prescription ratio of Example 3, configure 3 medicinal materials, each 187.5g, divided into four groups to test, the first group added 6 times the amount of water, 4 times the amount, the second group added 8 times the amount of water, 6 times the amount, the third Add 10 ti...

[0137] Experimental Example 2. Screening of the method for identifying the taste of each medicine in the Chinese medicine group and its contents of the present invention
[0138] Shoot dry
[0139] Method 1: Take the content of this pharmaceutical composition preparation equivalent to 40g crude drug, grind it into fines, add 50ml methanol, sonicate for 30 minutes, filter, evaporate the filtrate, add 40ml water to the residue to dissolve, add n-butanol to shake and extract three times , 20ml each time, combine the n-butanol solution, evaporate to dryness, add 2ml methanol to the residue to dissolve it as the test solution. According to the preparation method of the test product and the sample solution, prepare the negative sample solution of deficiencies; take another 1g of radican reference medicinal materials, add 15ml of methanol, sonicate for 30 minutes, filter, and concentrate the filtrate to 1ml as the reference medicinal solution. According to thin-layer chromatography (Chin...
experiment example 3
[0168] Experimental example 3. Screening of content determination method
[0169] The HPLC method is used to determine the content of icariin in the medicine of the present invention to improve the quality detection method of the present invention. Some test results are as follows:
[0170] ① Preparation of test solution
[0171] Take 20 tablets of this product, remove the film coating, grind finely, take about 1g, accurately weigh it, place a stoppered conical flask, accurately add 20ml of dilute ethanol, weigh it, and ultrasonically treat (power 250W, frequency 50kHz) , Let it cool, weigh it again, make up the lost weight with dilute ethanol, shake well, filter, and take the filtrate to get it. The content of icariin in the test solution was compared for different ultrasound time. The results are as follows:
[0172] Table 10 Selection of ultrasound time
[0173] Ultrasound time 20 minutes 40 minutes 60 minutes 80 minutes Icariin content (mg / g) 0.4307 0.6...
