Embodiment 1
[0038] Such as figure 1 The shown structure, the test card for quickly detecting the content of piroxicam in the traditional Chinese medicine for dispelling wind and dehumidification according to this embodiment, includes a housing and a test strip 4 arranged in the housing;
[0039] The housing includes an upper cover 1 and a lower cover 2 that are buckled together. The middle position of the lower cover is formed with a groove 3 for accommodating the test strip, and the other positions except the groove 3 are a PVC plate 6. The upper cover is provided with a sample hole 5 at a position corresponding to the test strip, so that the test liquid can be dripped onto the test strip;
[0040] The test strip is a test paper impregnated and loaded with an indicator, and the indicator is an aqueous solution including a ferric nitrate mass concentration of 20 wt%, a PEG200 mass concentration of 4 wt%, and a Triton X-100 mass concentration of 4 wt%.
[0041] The test card described in this emb...
Embodiment 2
[0052] Such as figure 1 As shown in the structure, the structure of the test card for quickly detecting the content of piroxicam in the traditional Chinese medicine for dispelling wind and removing dampness described in this embodiment is the same as that of embodiment 1.
[0053] The detection device for quickly detecting the content of piroxicam in traditional Chinese medicine for dispelling wind and dehumidification according to this embodiment includes: figure 1 The test card with the structure shown, and the intelligent immunochromatography and spectrum analysis integrated device disclosed in Chinese Patent CN105277680A, that is, the spectrum analysis handheld device. After the test solution undergoes the color reaction of the test card, the content of piroxicam in the test substance is read in the handheld device, which can be used as a judgment basis for rapid detection and screening of piroxicam quantitative detection.

Embodiment 3
[0064] The method for rapidly detecting the content of piroxicam in the traditional Chinese medicine for dispelling wind and removing dampness described in this embodiment includes the following steps:
[0065] (1) Take the traditional Chinese medicine pills for dispelling wind and removing dampness, grind them into granules, and weigh them; take 0.30g sample and place it in a 2ml centrifuge tube, add 1.5mL piroxicam extract (v ethyl acetate: v methanol = 2 : 1) Shake up and down for 30 seconds, centrifuge at 3000 rpm for 1 minute, and collect the supernatant, which is the test solution;
[0066] (2) Take ferric nitrate, PEG200 and Triton X-100 to dissolve in water respectively to prepare an aqueous solution of ferric nitrate mass concentration 20wt%, PEG200 mass concentration 4wt%, and Triton X-100 mass concentration 4wt%, which is The indicator, spare;
[0067] (3) Take 1ml of the liquid to be tested, and add 1ml of the indicator to mix, let stand for one minute, and observe the c...
