Embodiment
[0068] Asthma tablet detection methods include:
[0069] 1. Identification of Campanulaceae:
[0070] Weigh 0.5g of the fine powder of this product, put it in a stoppered test tube, add 2ml of 10% hydrochloric acid solution, bathe in water for 1h, take it out, centrifuge at 3500r / min for 10min, pour out the supernatant, adjust the pH to 9-10 with ammonia water, add 1ml of chloroform, Fully shake, 3000r / min centrifugal 10min, take chloroform layer as need testing solution; Another take 0.2g of bellflower contrast medicinal material, make contrast medicinal material solution with the same method; For the test, take 5 μl of each of the above two solutions, spot them on the same silica gel G thin-layer plate, use ethyl acetate: butanone: formic acid: water = 10:0.5:0.5:0.5 as the developer, develop, take out, and dry in the air , viewed under UV light (365nm). In the chromatogram of the test product, at the position corresponding to the chromatogram of the control medicinal mate...
