Embodiment 1

[0038] like figure 1As shown in the structure, the test card for quickly detecting the content of piroxicam in the traditional Chinese medicine for expelling wind and dampness described in this embodiment includes a casing and a test strip 4 arranged in the casing;

[0039] The shell includes an upper cover 1 and a lower cover 2 that are fastened together. A groove 3 for accommodating the test strip is formed in the middle of the lower cover. The other positions except the groove 3 are PVC boards 6, so The position of the upper cover corresponding to the test strip is provided with a sample injection hole 5, which realizes adding the liquid to be tested dropwise on the test strip;

[0040] The test strip is a test paper impregnated with an indicator loaded, and the indicator is an aqueous solution comprising 20 wt% of ferric nitrate, 4 wt% of PEG200, and 4 wt% of Triton X-100.

[0041] The detection card described in this embodiment is prepared according to the following meth...

Embodiment 2

[0052] like figure 1 As shown in the structure, the structure of the test card for rapid detection of piroxicam content in traditional Chinese medicine for expelling wind and dampness described in this embodiment is the same as that in Example 1.

[0053] The detection device for rapidly detecting the content of piroxicam in the traditional Chinese medicine for expelling wind and dampness described in this embodiment includes such as figure 1 The detection card with the structure shown, and the intelligent immunochromatography and spectral analysis integrated device disclosed in Chinese patent CN105277680A, that is, the spectral analysis handheld. After the liquid to be tested undergoes a color reaction on the detection card, the content of piroxicam in the substance to be tested can be read in the handheld device, which can be used as the judgment basis for the rapid detection and screening of piroxicam quantitative detection.

[0054] The setting method of the built-in curv...

Embodiment 3

[0064] The method for quickly detecting the content of piroxicam in the traditional Chinese medicine for expelling wind and dampness described in this embodiment comprises the following steps:

[0065] (1) Take the traditional Chinese medicine pill for expelling wind and dampness, grind it into granules, and weigh it; and take 0.30g of the sample and place it in a 2ml centrifuge tube, add 1.5mL of piroxicam extract (v ethyl acetate: v methanol = 2 : 1) Shake up and down for 30 seconds, centrifuge at 3000 rpm for 1 minute, collect the supernatant, which is the solution to be tested;

[0066] (2) Dissolve ferric nitrate, PEG200, and Triton X-100 in water respectively to make an aqueous solution with a mass concentration of ferric nitrate of 20wt%, a mass concentration of PEG200 of 4wt%, and a mass concentration of Triton X-100 of 4wt%, which is The indicator, standby;

[0067] (3) Take 1ml of the solution to be tested, add dropwise 1ml of the indicator to mix, let it stand for ...

Abstract

The invention belongs to the technical field of detection of traditional Chinese medicine preparations, particularly relates to a detection card for rapidly detecting content of illegally added piroxicam (PIR) in traditional Chinese medicine preparations capable of dispelling wind and eliminating dampness and further discloses a method for rapidly detecting content of illegally added piroxicam intraditional Chinese medicine preparations capable of dispelling wind and eliminating dampness. Through the detection card for rapidly detecting content of the illegally added piroxicam in traditionalChinese medicine preparations capable of dispelling wind and eliminating dampness, reaction processes of extracting and developing the piroxicam in traditional Chinese medicine preparations are capable of rapidly carrying out qualitative detection of piroxicam added in the traditional Chinese medicine preparations; a handheld machine capable of carrying out qualitative analysis in the prior art isused for carrying out qualitative detection of the content of piroxicam; the detection card can be used for carrying out rapid on-site detection on the content of the chemical component which is piroxicam in Chinese patent medicines capable of dispelling wind and eliminating dampness; the defects of high cost and high time consumption of the existing instruments are overcome; the problems of highpossibility of occurrence wrong detection and detection omission due to diversity of interference factors in the samples of the existing kit are solved.

Description

technical field [0001] The invention belongs to the technical field of detection of traditional Chinese medicine preparations, in particular to a detection card for quickly detecting the content of illegally added piroxicam in traditional Chinese medicine preparations for dispelling wind and dampness, and further discloses a method for rapidly detecting the content of illegally added piroxicam in traditional Chinese medicine preparations for dispelling wind and eliminating dampness . Background technique [0002] Piroxicam (Piroxicam, referred to as PIR), chemical formula C 15 h 13 N 3 o 4 S, chemical name 2-methyl-4-hydroxy-N-(2-pyridyl)-2H-1 or 2-benzothiazine-3-carboxamide 1,1-dioxide, trade name also known as An Erke, piroxicam, piroxicam, piroxicam, Xipukang or Feiding are a new type of non-steroidal western medicine, which have obvious analgesic, Anti-inflammatory and detumescence to a certain extent, with a high cure rate. [0003] At present, the expelling wind...
