[0092] 3. Preparation of the test solution

[0093] (1) Selection of extraction solvent

[0094] Because the Tinglizi formula granule is concentrated from the water extract of Tinglizi, it has strong water solubility. The extraction effect of pure water, 25% methanol aqueous solution, 50% methanol aqueous solution, 75% methanol aqueous solution and 100% methanol on the Tinglizi formula granules was investigated, and the percentages here are methanol volume percentages.

[0095] The specific experimental method is as follows:

[0096] Take an appropriate amount of this product, grind it finely, take about 0.2g, accurately weigh it, put it in a stoppered Erlenmeyer flask, accurately add 25ml of different solvents, weigh it, ultrasonically treat it (frequency 37kHz, power 1130W) for 15 minutes, let it cool, Weigh again, make up the lost weight with different solvents, shake well, centrifuge at 12000rpm for 10 minutes, filter, and take the filtrate to obtain the final product. ...
