Embodiment 1
[0441] TLC Identification of Radix Astragali in Example 1 Tablets
[0442]Take the sample to be tested, grind it finely, take an appropriate amount of powder, add ethanol to extract, filter, evaporate the filtrate to dryness, add 0.3% sodium hydroxide solution to dissolve the residue, filter, adjust the pH value of the filtrate to 5-6 with hydrochloric acid, and use ethyl acetate to Extract the ester, filter, evaporate the filtrate to dryness, add ethyl acetate to the residue to dissolve, and use it as the test solution; take another Astragalus control medicinal material, and prepare the contrast medicinal material solution in the same way; adopt thin-layer chromatography test, absorb the above-mentioned test solution and An appropriate amount of the control solution was spotted on the same silica gel G thin-layer plate, developed with chloroform-methanol = 10:1 as the developer, taken out, dried in the air, smoked in ammonia vapor, and then inspected under a 365nm ultraviolet ...
Embodiment 2
[0443] TLC Identification of Radix Astragali in Example 2 Pellets
[0444] Take the sample to be tested, grind it finely, take an appropriate amount of powder, add methanol to extract, filter, evaporate the filtrate to dryness, add 0.05% sodium potassium hydroxide solution to dissolve the residue, filter, adjust the pH value of the filtrate to 3-4 with hydrochloric acid, and use three Extract with methyl chloride, filter, evaporate the filtrate to dryness, add ethyl acetate to dissolve the residue, and use it as the test solution; take another Astragalus reference medicinal material, and prepare the reference medicinal material solution in the same way; use thin-layer chromatography to test, draw the above-mentioned test solution respectively Take an appropriate amount of the control solution, spot on the same silica gel H thin-layer plate, develop with dichloromethane-methanol=3:1 as the developer, take it out, dry it in the air, and inspect it under a UV lamp at 254nm. In the...
Embodiment 3
[0445] Thin-layer chromatography identification of Radix Astragali in embodiment 3 granules
[0446] Take an appropriate amount of the sample to be tested, add 50% ethanol to extract, filter, evaporate the filtrate to dryness, dissolve the residue with 5% ammonia solution, filter, adjust the pH value of the filtrate to 4-5 with hydrochloric acid, extract with chloroform, filter, The filtrate was evaporated to dryness, and the residue was dissolved in ethyl acetate, which was used as the test solution; another reference medicinal material of Astragalus membranaceus was prepared in the same way as a reference medicinal solution; the thin-layer chromatography test was used to absorb the appropriate amount of the above-mentioned test solution and control solution, and point on On the same silica gel G thin-layer plate, use chloroform-ethanol=10:0.2 as the developing agent, develop, take out, dry, put in ammonia vapor and smoke and then inspect under the ultraviolet lamp at 365nm.
