Embodiment 1
[0028] Embodiment 1 The methodological verification of the quality control method of the present invention
[0029] (1) Accuracy test
[0030] like figure 2 As shown, when determining the total flavonoid content in Shenshitong extract or Shenshitong preparation, the rutin standard solution and the test solution have a common absorption peak at 273nm wavelength, indicating that this method is suitable for the determination of total flavonoids in Shenshitong The accuracy test shows that the recovery rate of this method can reach 100.1%, and the measurement results are reliable, as shown in Table 1.
[0031] Table 1 Accuracy test results
[0032]
[0033]
[0034] (2) Precision test
[0035] The precision test shows that the method has good precision, as shown in Table 2.
[0036] Table 2 precision test results
[0037]
[0038] (3) Stability test
[0039] The time-coursre test showed that the absorbance value did not change within 180 minutes, as shown in Table 3...
Embodiment 2
[0047] The quality control method of embodiment 2 Shenshitong extract
[0048] It includes the steps of ingredient identification and determination of total flavonoid content.
[0049] A. Composition identification:
[0050] (1) Take 4g of this product, evaporate to dryness, add 30ml of 65% ethanol, ultrasonically treat for 30 minutes, filter, evaporate the filtrate to dryness, add 10ml of water to dissolve the residue, shake and extract 5 times with ether, 10ml each time, discard the ether solution , then shake and extract with 10ml of ethyl acetate, evaporate the ethyl acetate extract, add 1ml of 95% ethanol to the residue to dissolve it as the test solution; take another 1g of desmodium as reference drug, and make the reference drug solution in the same way. Take 10 μl of each of the above two solutions, spot them on the same polyamide film, use glacial acetic acid-water (2:1) as developer, develop 15 cm, take it out, dry it in the air, spray with 3% aluminum trichloride e...
Embodiment 3
[0062] Example 3 The quality control method of Shenshitong Granules (specification: 15 grams per bag, containing 7.65 grams of crude drug) includes the steps of component identification and determination of total flavonoid content.
[0063] A. Composition identification:
[0064] (1) Take 20g of this product, grind it finely, add 50ml of 65% ethanol, ultrasonically treat (power 250W, frequency 33KHz) for 30 minutes, filter, evaporate the filtrate to dryness, add 30ml of water to the residue to dissolve, shake and extract 5 times with ether, 30ml each time, discard the diethyl ether solution, then shake and extract with 30ml ethyl acetate, evaporate the ethyl acetate solution to dryness, add 1ml of 95% ethanol to the residue to dissolve, and use it as the test solution. Take another 1 g of Desmodium as reference medicinal material, and prepare the reference medicinal material solution in the same way. Take 4 μl of each of the above two solutions, spot them on the same polyamid...
