experiment example 1
[0032]Experimental example 1 Research on the determination method of total alkaloid content in Fritillaria chinensis
[0033] The total alkaloid content was used as the evaluation index. To establish an acid dye colorimetric method to determine the content of total alkaloids in Fritillaria fritillata.
[0034] Preparation of solution
[0035] Buffer solution: take 0.2mol L -1 Potassium hydrogen phthalate dissolved in 100mL (4.08g), with 0.2mol·L -1 Add about 50mL (0.4g) of sodium hydroxide solution and adjust the pH value to 5.0.
[0036] Bromothyme Finnish solution: weigh 0.03 g bromothymol blue, dissolve in 0.5 mL, 1mol L -1 Sodium hydroxide solution, add distilled water to dilute to 100mL and shake well.
[0037] Reference substance solution: Accurately weigh 2.55 mg of peiminin B reference substance, and dilute it in a 25mL volumetric flask with chloroform as the reference substance solution.
[0038] Preparation of sample solution: Precisely weigh 2.00 g of Fritilla...
experiment example 2
[0056] Experimental example 2 Research on the extraction process of total alkaloids in Fritillaria
[0057] Using the ethanol reflux extraction method, taking the total alkaloid extraction as the evaluation index, the extraction process parameters such as solid-liquid ratio, extraction time, and ethanol concentration were optimized through orthogonal experiment design.
[0058] Raw material handling
[0059] The raw material medicine of Fritillaria fritillaria is taken to remove impurities, washed, dried and crushed to obtain coarse powder for later use.
[0060] Extract sample preparation
[0061] Flat Fritillaria coarse powder→ethanol reflux extraction twice→filter, combine the filtrates→concentrate the filtrate under reduced pressure, evaporate to dryness→add chloroform to the residue in a 25mL volumetric flask→accurately measure 2mL into a 25mL volumetric flask , that is.

[0084] Experimental Example 3 Research on Ginseng Processing Technology
[0085] The monarch drug in the composition of the present invention is ginseng. Because ginseng is a precious medicinal material, the formula adopts the method of crushing and sieving the ginseng, directly using the fine powder as medicine, and further extracting the coarse powder to fully utilize the ginseng. The method is as follows: the ginseng is pulverized, passed through a 120-mesh sieve, the sieved fine powder is used for standby, and the unsifted coarse powder is extracted.
[0086] 3.1 Investigation on the powder yield of ginseng crushing
[0087] The ginseng was crushed with a universal grinder, and the powder extraction rate was examined through a 120-mesh sieve. The results are shown in Table 6. The results show that the powder extraction rate of pulverized ginseng fine powder according to this method is 87.04%.
