Examples
Embodiment 1
[0074] Commercially available health food A (tablets, the labeled dosage is 2 tablets each time, and the test results of high performance liquid chromatography contain 0.7mg of chlorpheniramine maleate in each tablet of this product)
[0075] Take one piece of this product, crush it, put it in a sample tube, add 10ml of water, shake for 1min, filter, take 2ml of the filtrate as the test solution; take 0.2g of chromotropic acid, add 100ml of water to dissolve it, and use it as a color reagent Add 0.5ml of chromogenic reagent to the test solution, add 0.1ml of acetic acid-sodium acetate buffer solution (PH=4.5) to the test solution, shake for 30s, then add 5ml of dichloromethane, shake and mix evenly, After layering, the dichloromethane layer turns into a color between pink and light pink, so it can be judged that the sample contains illegally added chlorpheniramine maleate components, and at the same time, the content of chlorpheniramine maleate is 0.2 Between ~0.1mg, multiplie...
Embodiment 2
[0077] Commercially available health food B (capsules, the labeled dosage is 1 capsule each time, and the test result of high performance liquid chromatography is 1.16mg of chlorpheniramine maleate per capsule of this product)
[0078] Take one grain of this product, put it in a sample tube, add 10ml of water, shake for 1min, filter, take 2ml of the filtrate as the test solution; take 0.2g of chromotropic acid, add 100ml of water to dissolve it, and use it as a color reagent ; Add 0.5ml of chromogenic reagent to the test solution, add 0.1ml of acetic acid-sodium acetate buffer solution (PH=4.5) to the test solution, shake for 30s, then add 5ml of dichloromethane, shake and mix well, let stand After layering, the color of the dichloromethane layer becomes between pink and pink, so it can be judged that the sample contains illegally added chlorpheniramine maleate ingredients, and at the same time, the content of chlorpheniramine maleate is between 0.4-0.2 mg, multiplied by the d...
Embodiment 3
[0080] Commercially available health food C (capsules, the labeled dosage is 2 capsules each time, the test results of high performance liquid chromatography for this product are 1.04mg of chlorpheniramine maleate per capsule)
[0081] Take one grain of this product, put it in a sample tube, add 10ml of water, shake for 1min, filter, take 2ml of the filtrate as the test solution; take 0.2g of chromotropic acid, add 100ml of water to dissolve it, and use it as a color reagent ; Add 0.5ml of chromogenic reagent to the test solution, add 0.1ml of acetic acid-sodium acetate buffer solution (PH=4.5) to the test solution, shake for 30s, then add 5ml of dichloromethane, shake and mix well, let stand Put the layers, the dichloromethane layer turns pink, so it can be judged that the sample contains illegally added chlorpheniramine maleate components, and at the same time, the content of chlorpheniramine maleate is close to 0.2mg, multiplied by the dilution factor = 5 , It is judged tha...
